LAND NAVIGATION WITH MAP
AND LENSATIC COMPASS


LAND NAVIGATION
Why Learn Land Navigation? Training and practicing land navigation on foot
provides the following everyday navigation (how not to get lost) benefits;
- Tracking present location (Where am I ?)
- Determining Distance (How far is it and am I there yet ?)
- Sense of direction (Where do I want to go and where am I actually going ?)
- How to read a topographic map (Do I understand the map ?)
-Terrain and map association (What hill or river am I looking at ?)
- Spatial skills (Can I mentally visualize the landscape in 3D ?)
- Planning safe, practical routes (Take a long safe route or a short risky route ?)
- And more Navigational skills
The best way to learn LAND NAVIGATION is to get "dirt time", that is, get out there with a map and compass!
Navigation is not about finding yourself after you are lost (although that’s what happens sometimes); it’s about
keeping track of your position as you move away from a known point. As you move you have to remain
cognizant of the terrain you are leaving, of the terrain you are passing, and of the terrain that is ahead.
Navigation in the wilderness means knowing your starting point, your destination, and your route to get there.
These skills will allow you to venture farther off the beaten path than you ever thought before.

PLANNING TO NAVIGATE
DESCRIPTION
EVERY TIME you enter a wilderness area, familiar or not, alone or
in a group, you should prepare as though you were going in alone.
In spite of rules for following the leader’s decisions, or those of
the majority, and rules for keeping the group together (as well as
rules for not going alone) the plain truth is that in the wilderness an
individual is potentially a unit of one.
Always “BE PREPARED”. Leaders have been known to fail, and
the group’s best of intentions do not always keep a group together.
Example, in a group of three - one of them sustains a serious
injury and the other must stay with the injured person, while the
third person goes for help. The third person now becomes a
navigator, regardless of whether or not the person was one.

• Enjoying the great outdoors means navigating, perhaps camping overnight and then moving on again.

• It is important to have all the right equipment, and have a travel plan, with safety always in mind.
Planning ahead (research) can prevent future frustration. To do this, you must think about the following.
– The Group or traveling alone (individual strengths and weaknesses, physical and mental needs)
– Equipment (essentials and comforts)
– Safety (rules to follow, emergency plans)
– Responsibilities (group or traveling alone)
– The terrain (a detailed map study, weather)
– Route selection ( practical routes, alternate routes, the group type)


GROUP or ALONE
GROUP
• Choose your group carefully (unless it is a family trip) - if people are stubborn, inflexible and finicky at
home, they will be even more so in the wilderness.
• Leader - a group must elect a leader, who should asses the capabilities of each individual before making
plans to travel. A leader must have competence and the skills to lead a group. Above all, the leader must
at all times avoid the appearance of indecision.
• Leadership - is very difficult, especially under the pressure of Life-or-Death situation, and particularly if
some people, within the group, are unwilling to be led.
 There are four types of leadership and all are equally important.
~ Designated Leadership - taking responsibility for the group, motivating and guiding the group
toward its goals, and determining how the group will achieve these goals.
~ Group Leadership (Active Followership) - supporting and following the designated leader,
and participating in ―group decision making‖ by giving input and seeking clarity.
~ Peer Leadership - the team works together and supports each other in achieving group
goals, and each team member sees what needs to be done and does it.
~ Self Leadership - each person takes care of themselves, so they can take care of the group,
and everyone shows personal initiative and character.
• Individual strengths and weaknesses – must be carefully and privately considered by the leader,
whose plan of action will be determined by what the group as a whole is capable of doing. Each individual
must know and except their own strengths and weaknesses.
• Physical and mental needs – the group will have a better time if its needs are met and stays together;
its integrity maintained through good, caring, leadership. Like medications, eyewear, hearing aids,
socializing, feeling needed, eliminate boredom, etc.


GROUP or ALONE
ALONE
• The more experience you have navigating and camping with others, the better qualified you are to go it
alone.
• Remember, all of your experiences, good and bad, become more intense when you are alone.
• Trekking the wilderness alone for any number of reasons entails much greater risks from the
consequences of injury or becoming lost than trekking with a group does.
• These are risks that you personally and willingly accept for the rewards of solitude.
• Ironically, the reward for trekking solo is a heightened awareness of potential dangers and a stricter
adherence to safety concerns.
• A person who has spent a vast amount of time in the wilds alone, is more careful than a person who has
someone to watch their back.
 You look at the cliff a little longer before deciding if it’s safe to climb. Or find a safer spot to cross a
river.
• Individual strengths and weaknesses – you must know and except your own strengths and
weaknesses.
• Physical and mental needs – you must asses your own needs, like medications, eyewear, isolation,
boredom, etc.
• A solitary wanderer becomes more conscious about leaving a note behind.


EQUIPMENT
ESSENTIALS
• Without a doubt the single most important item in your gear is YOU.
 A clear, cool head (mind) atop a body in good physical and mental condition.
 An adventurous spirit.
 And good common sense.
• How much gear is needed? Just enough to stay dry, warm, and nourished. A light pack will allow for
increased awareness and enjoyment of the surroundings while in route to your destination.
• Individuals - must have these twelve (12) essential items in a daypack.
1. A PLAN - never travel without it. 5. Whistle 9. Emergency rain gear
2. Map 6. Personal first-aid kit 10. Flashlight
3. Compass 7. Insect repellant/sun screen 11. Water
4. Pocket knife 8. Matches, waterproof 12. Food
 Backpacking (campsite essentials)
1. Tent & tarp 4. Individual stove & fuel 7. extra food
2. Sleeping bag & pad 5. Water purifier 8. toiletries
3. Eating / cooking utensils 6. Extra clothing 9. binoculars
• Groups - any additional gear for the group to complete their goals. Carrying these extra items will be
distributed among the group as evenly as possible by weight.
COMFORTS
• What are comforts? Non-essential gear not listed above, such as a chair, radio, pillow, reading book, etc.
• Determine the comfort gear that YOU NEED to maintain your personal level of security and comfort.
Also, note that you must carry your own personal comfort gear.


SAFETY
• Leave copies of your plans, destination and schedule, with a family member or Ranger Station.
• Always carry your daypack, with the twelve essentials, with you.
• In a group - pace the hike to the slowest member of the group. STAY TOGETHER, start as a group, hike
as a group and end as a group. Always use the buddy system.
• Each member should study the planned route on the map and have their own copy of the map & route.
• The group should come up with safety rules that are adhered to and enforced by all.
• In a group - when navigating, divide responsibilities.
 SCOUT – selecting the best path (footing), avoiding dead falls, loose rocks, etc.
 NAVIGATOR – makes sure the SCOUT stays on course.
 HEAD COUNT – at intervals stops the group and the group does a head count.
 EQUIPMENT – at intervals (during head count) perform group and personal equipment inventory.
 EVERYONE - keep a lookout for hazards, and keeps all persons in visual and talking range.
• When a group or lone navigator cannot know for certain where they are going, they had better be certain
of where they have been. They must in some way remain oriented to their base camp, the trail head, or
some other point which means food and shelter (safety).
 Check your approximate location on the map and try to compare its markings with your
surroundings. Do this every 30 minutes to an hour. Sooner, if the group desires.
• Bad weather or unexpected hazards, turn back and return to base camp (safety). DO NOT take any risk.
• Pre-trip equipment check; make sure everything works and that you know how to use it.


SAFETY

THE RULE OF THREE’S
3 SECONDS – (MIND) the time you have to decide to escape or take action on an immediate danger.

3 MINUTES – (AIR) the average time you can survive without breathable air.

3 HOURS – (SHELTER) without it, time before you start dying from hypothermia (cold) or hyperthermia (heat).

3 DAYS – (WATER) the time before dehydration can claim your life because lack of water.

3 WEEKS – (FOOD) the time before you cannot do any daily necessary task because of lack of food.

3 MONTHS – (HOPE) the time without meeting anybody else before a solid depression catches you.


RESPONSIBILITIES
• Alone you have the responsibility to keep yourself physically and mentally alert, aware, and safe.
• In a group everyone needs a responsibility; this gives a person the satisfaction of belonging to a team.
• In a group - when navigating, divide responsibilities and rotate the responsibilities.
* * * It is possible for one person to hold more than one position if need be. * * *
 # 1 SCOUT (point man) – selects the best path (footing), avoiding dead falls, loose rocks, hazards.
DOES NOT go fast and after an obstacle waits and allows everyone to catch-up before moving on.
 # 2 NAVIGATOR (compass) – ensures the SCOUT/group stays on course, with map and compass.
 # 3 LEADER – at intervals stops group for rest period, keeps all group members within visual and
talking distance. Makes sound decisions at a moment’s notice, taking into consideration the current
situation as well as all possible contingencies. Consults with the ASSIST LEADER.
 # 4 PACE COUNT – keeps track of how far the group has traveled by pace count and time.
 # 5 ASSIST NAVIGATOR (compass) – ensures the group stay on course, with map and compass.
 # 6 ASSIST PACE COUNT – keeps track of how far the group traveled by pace count and time.
 # 7 HEAD COUNT / EQUIPMENT – during rest period ensures the whole group does a head count,
a personal equipment inventory, and takes in nourishments (water and food).
 # 8 REAR (Assist Leader) – keeps a lookout for hazards from behind and makes sound decisions
at a moment’s notice. If someone in the back of the group needs to stop, relays message to Leader
to halt group. Consults with the LEADER.
NOTE – primary and assistant positions must compare findings with each other, to verify results.

THE TERRAIN
TERRAIN
• Review park brochures, internet photos, maps, and all other sources, to get a visual of the landscape.
• Detailed map study – take a good look at the map before you pack for the wilderness.
 It will show you treasures and obstacles along the way.
~ A great ridge top for a breathtaking view.
~ A challenging water crossing.
• Elevations can tell you where you may encounter snow (high elevations) in early summer.
• Contour lines will show steep or gentle slopes on a planned route.
• Maybe you need special equipment to cross difficult terrain.
• Seasonal considerations.
 Rainy Season – has that small stream turned into a raging flooded uncrossable river?
 Dry Hot Season – that water hole or small stream you planned to take a rest at, is it dried up?
 Are there dangers of seasonal wildfires?
• Timing is everything.
 What can be an easy low water stream crossing in the early morning can become a dangerous or
impassable river by the afternoon.
 That swamp full of bugs in the morning may be easier to navigate in the evening high winds.


ROUTE SELECTION
ROUTE SELECTION
There are two types of routes.
 A route that fits the group or solo person – physical and hiking skills are limited. No experience.
 A group or solo person that fits the route – the route is so challenging and requires special skills.
• Will it be a loop route (point ―A‖ to ―A‖) or a one-way route (point ―A‖ to ―B‖)?
• Select a group and routes with the right qualifications.
 What type of group is it? Informal (friends) or formal (paying customers, educational class)?
 What are the goals of each group member? Do they want to be there or do they have to be there?
 What is the experience level of each member?
 Are there group members that can lead and manage the group?
 What is the physical condition of each member?
 Are there health issues among the group?
 Plan the routes at a level that will be fun, educational, challenging, and safe for everyone.
• Use binoculars –they save a lot of legwork. Survey the area from different vantage points, trying to
understand where streams and rivers flow, lay of the hills, terrain footing and obstacles, etc.
 Scanning – scan very slowly, looking hard into, rather than at, the terrain.
• Expect the unexpected.
 Select routes that can be modified for unseen situations.
~ Bad weather
~ Trail conditions
~ Broken equipment
~ Injuries, etc


STAYING ON COURSE
DESCRIPTION
The difference from classroom into the
wilderness is the difference between THEORY
and PRACTICE.
The wilderness is not crisscrossed with
reference grid lines, like a map, to aid the
navigator.
There is difficulty encountered in holding to
a selected course under conditions where the
objective cannot be seen.

• Wilderness navigation is a DISCIPLINE when traveling off the beaten path. To stay on course DO NOT
rely on your ―sense‖ of direction. You must rely on your compass and all navigation techniques available
to you.
– Human reference point
– Making a reference point
– Baselines
– Thumbing the map


STAYING ON COURSE
HUMAN REFERENCE POINT
1. Navigator #1 stays stationary, while navigator #2 goes ahead to the limit of visibility.
• With binoculars and walkie-talkies, the distance can be further.
2. Then navigator #1, with compass in hand at desired azimuth, signals navigator #2 to move left or right
till navigator #2 is aligned with compass azimuth bearing.
3. Navigator #1 catches up with navigator #2 and the process is repeated.
NAVIGATOR #2

NAVIGATOR #1

NOTE
By keeping track of distance as well as the direction of each zig & zag while traveling, and doing some careful
map work, the group will have a running assessment of their approximate location.

STAYING ON COURSE
MAKING A REFERENCE POINT
As a lone navigator, this is an alternate method to the ―human reference point‖ when resources are available.
However, it is time consuming to assemble.
1. At your current position, pile up rocks or other landscape debris laying around.
2. Ensure it is large enough to be seen from a long distance away on your route.
3. Set your desired azimuth, say 125º and calculate your back azimuth (125º + 180º = 305º back azimuth).
4. Walk as far as you can on your desired azimuth 125º, occasionally looking back to the reference point
and checking the back azimuth 305º to the reference point, as you walk forward.
5. Move left or right to maintain the back azimuth 305º, which keeps you on course, eliminating lateral drift.

AZIMUTH


STAYING ON COURSE
BASELINES ADVANCED
Azimuths can serve as baselines that let you explore a ―trail less‖ area from your camp sight.
1. You create a baseline with the first azimuth measured from your camp (starting point) to a landmark (58º peak 1).
2. Taking a second azimuth landmark (340º peak 2) fixes the campsite’s exact location on the first azimuth baseline.
3. With the cross azimuths written down you’re free to wander around the area.
4. You explore the area and sight on peak 1 to find your azimuth is 354º, which puts you east of the baseline.
5. You head west towards the baseline till your azimuth to peak 1 is 58º, which puts you on the baseline.
6. Now you are at the baseline of 58º, but which way to turn, to go to camp? West or east?
7. You sight on peak 2 to find your azimuth is 38º, which puts you west of camp, so you turn east.
8. Walk the 58º baseline till peak 2 is 340º, if you don’t stray off the baseline, you will reach the camp sight.

NOTE
To avoid getting off
course from the
baseline, remember to
make use of
intermediate landmarks
along the baseline,
keeping close track of
deviations as you make
them, and correct for any
detours, get back to the
baseline as soon as
possible.


STAYING ON COURSE
BASELINES ADVANCED
Going somewhere you cannot see - You want to
travel to a destination beyond a group of hills.
START
1. On the map; mark your start and finish points.
2. Choose the best route between them and draw
the route legs.
3. Using a protractor; determine the route leg
azimuths on the map and estimate distance
between each leg of the route.
4. Locate features or landmarks on the map that will
help you identify each leg junction on arrival;
such as junction 1 (hill at 139º and hill at 185º)
MN azimuth on the compass or use ―Pace & Time
Count‖.
5. Write them down on the map or on a paper and
follow your bearings (BASELINES).

NOTE
If you have MN LINES drawn on the map, align the
protractor to a MN LINE and get the MN azimuth, you
DON’T have to do any MN conversions for compass.

HERE IS ANOTHER EXAMPLE

Here you use intermediate landmarks as
LEG ( x ) JUNCTIONS.

• LEG 1 starts at base of hill
• LEG 2 starts between two hills
• LEG 3 starts between three landmarks
( stream, ridge spur, and hill ).
• LEG 4 starts between two orchard fields and
ends at road junction.

• Note: ―CP‖ stands for ―Check Point‖. ANY
visual land mark reference, to ensure you
are still on the right course to your goal.
CP1 = between hills
CP2 = church building
CP3 = orchard field


STAYING ON COURSE
THUMBING THE MAP
It is a great technique that will keep you from getting lost goal
or confused. As you gain skill, it becomes a great
technique for increasing your travel speed as well! It is
based on maintaining map contact.

1. Fold the map so it is more manageable. (see map folding
techniques – Part 1 Basic land Navigation)

3. Hold your map in one hand with your thumb close behind
your location (don't cover it up). now
4. Shift your thumb on the map as you progress on the ground. you are
here
5. When you come to an obvious feature on the map and on the
ground, shift your thumb to mark your new location.
6. Keep your thumb on your map as a "You Are Here" marker
and you'll save yourself lots of time and confusion! Shift

for normal navigation. And there are other ways to thumb the
map, i.e. use a pencil to quickly mark your location, as you travel.


ADDITIONAL NAVIGATION SKILLS
DESCRIPTION
You already have been given Land Navigation techniques to give
you a good start in becoming a competent navigator. You have
learned how to operate your own lensatic compass with a map and
other LAND NAVIGATION TECHNIQUES in Parts 1 and 2 of these
lessons, plus “Part 3 Advance Land Navigation” skills.
Here you will find additional wilderness navigation SKILLS THAT
WILL GREATLY AID YOU in navigating the wilderness and improve
your Land Navigation experience level.

• These additional skills, when used, will provide you with essential data. Information that will aid you in
making necessary decisions in various situations.
— Estimating how much daylight is left
— Binoculars with internal compass & rangefinder
— Estimate distance with Lensatic Compass MILS
— Conserve energy
~ Rest break durations, 4 minutes or 30 minutes, and why
~ Rhythmic breathing
~ The ―Rest Step‖
~ Walking sticks
— Blisters
— Weather prediction


ESTIMATING DAYLIGHT
Knowing the TIME of sunrise and sunset for the area you are hiking and having a watch with you is
something you should know and have. Example; sunrise is 6:30am and sunset 7:15pm, you have 12 hrs 45
mins of daylight. And with a watch, while hiking, you can know how much daylight is left before it gets dark.
However, if you do not know the TIME of sunrise and sunset, you can calculate the hours of daylight left
with your hands. Reaching your destination before it gets dark is important. To estimate when the sun will
disappear behind a hill, ridge, horizon, or canyon floor. . .
1. Hold both your hands at arms length, palms facing you and fingers horizontal.
2. Line up the bottom of the sun with the top of the upper finger with one hand, and the other hand lined up to
the bottom of the other hand.
3. Count the number of fingers to the horizon.
4. Every finger is about 15 minutes of daylight left before sunset.

2 hours

30 minutes 1 hour and 30 minutes


BINOCULARS WITH COMPASS & RANGEFINDER
• This item is a luxury, BUT is a very useful luxury.
• The compass alone is a quick way to find An azimuth to a very far away distant landmark.
• The range finder is very easy to use and the data received from it is invaluable.



IMPORTANT: Always remember that the
Distance and Object Size scales are in a ―ratio‖
to each other. When you add ―0’s‖ to one, you
must add an equal number of ―0’s‖ to the other.

. . .


When the object size is known, its distance is determined as follows:
1. Look through your binocular and place the horizontal reticle line at the base of the object.
2. Count the number of reticle divisions from the base to the top of the object. (In the example on the
previous slide, the top of the lighthouse comes to 2.5 on the Reticle Scale)
3. Rotate the Calculator Dial and place this number (2.5) at the Angle Index Mark
4. Assuming you know that the height of the lighthouse is 100 ft., look below the Angle Index Mark and find
the object size on the scale labeled ―Object Size‖. In this example, use ―10‖.
NOTE
The object size divisions are from 1 to 20. In dealing with an object that is
100 feet, mentally add a zero to the 10 indicator on the object size scale.
5. Now read the distance scale directly beneath the object size. It is 400 but remember, because you added
a ―0‖ to the ―10‖ in Step 4, you must add a zero to the 400. Thus, the distance from you to the lighthouse
is 4000 feet.
When distance to the object is known, its size is determined as follows:
1. Count the reticle divisions occupied by the object
2. Rotate the Calculator Dial, so that the Angle Index Mark points to the number from the reticle scale .
3. Look at the Distance Scale, and find your known distance to the object (for example, 4000 feet, or 400 on
the scale). The number on the Object Size scale that is opposite this distance indicates the size of the
object (for example, 100 feet).


( Using binocular ring calculator )
• Map indicates Landmark is 100 yards wide. • Both hikers are about 5’4‖ tall.
• Landmark covers 4 marks on binocular scale. • Hiker covers 1½ (1.5) marks on binocular scale.
• You are 1000 yards away from landmark. • Hikers are 950 feet (316 yards) away from camp.
• At your current speed, 30-40 minutes away. • 10-15 minutes before they reach camp.

• m is the angular width (height) of the object in MILS.
Width
• W (H) is the width (height) of the object in meters.
• R is the range or distance in thousand (1000) meters.

Landmark is 92 meters (100yds) Width
binocular total tick mils is 40mils
92W . 40m = 2.3 x 1000 meters = 2300 meters (2.3Km or 1½ miles)

ESTIMATING DISTANCE WITH COMPASS MILS (Technique 1)
This technique is used with landmark information • Range (distance) = W . m
.
Landmark is 92 meters (100yds) Width • Width = R x m

Azimuth of the left side of landmark is 5200mils W (H)
• m= R
R
Azimuth of the right side of landmark is 5300mils
• m is the angular width (height) of the object in MILS.
Compass mils is 5300 – 5200 = 100mils
• W (H) is the width (height) of the object in meters.
92 100 = 0.92 x 1000 meters = 920m (1,006yds) • R is the range or distance in thousand (1000) meters.

5200mils 5300mils


ESTIMATING DISTANCE WITH COMPASS DEGREES
This technique is good to use when you DO NOT HAVE A MAP. A Lensatic Compass is the best type of compass to use, it is easy to sight a landmark and is accurate.
1. You see a far away hill that you want to know the distance to, so you take a bearing reading to a spot on the hill. (Example 75 degrees)
2. You then walk perpendicular (right angle) to a measured distance. (Example 100 meters)
3. Then take another bearing reading to the exact same spot on the hill. (Example 80 degrees)
4. Next find degree difference and use the calculation to get the distance to the hill.
Deg Tangent Deg Tangent Deg Tangent d = ((Tan (90 - (A -B))) x Ref ) d = ((Tan (90 - (A -B))) x Ref )
1 0.017 31 0.601 61 1.804
2 0.035 32 0.625 62 1.881 80 degrees A = Greater value of measured bearing angles 1. (A – B) 80 – 75 = 5
3 0.052 33 0.649 63 1.963 75 degrees B = Lower value of measured bearing angles 2. (90 - (A-B)) 90 – 5 = 85 Deg

9 0.158 39 0.810 69 2.605 Note: When you have a degree that reads less that 360 and the other more that 360 (0 degrees), example
10 0.176 40 0.839 70 2.747 358 degrees and 3 degrees, all you are looking for is the degree difference, just like the above example.
11 0.194 41 0.869 71 2.904 3 + 360 = 363, so you subtract 363 – 358 = 5. Tangent would be the same as above; 90 – 5 = 85 so the

ESTIMATING DISTANCE WITH COMPASS DEGREES
THIS TECHNIQUE IS A SIMPLIFIED VERSION OF THE PREVIOUS SLIDE.
NOTE: You can use any degree that is at least 1 degree or more.

1. You see a far away hill that you want to know the distance to, so you take a bearing reading to a spot on the hill.

2. You then walk perpendicular (right angle) till you reach an off-set of at least 1 degree. (This example is 2 degrees)
NOTE: The further the landmark, the more distanced walked is needed to get a minimum of 1 degree difference
and the closer the landmark, the less distance walked is needed.

3. Then measure the distance walked from start to finish. (This example is 18 meters)
NOTE: you can use centimeters, meters, feet, yards or any measurement value.

4. Next use the calculation to get the distance to the hill.

5. Use this information to plot your location on the map, using one of the azimuths and distance on your calculation.

515 meters (0.5 Km) = 28.636 x 18 meters


ESTIMATING DISTANCE WITH COMPASS MILS (Technique 2)
This technique is good to use when you DO NOT HAVE A MAP. And a Lensatic Compass is the best type of compass to use, because it is easy to sight a landmark and
is more accurate when you use the MILS scale.
Use the same technique from the previous slide.

ESTIMATING DISTANCE WITH COMPASS MILS
NOTE: THIS TECHNIQUE IS A SIMPLIFIED VERSION OF THE PREVIOUS SLIDE.
NOTE: You can use any mils that is at least 10 Mils or more.

1. You see a far away hill that you want to know the distance to, so you take a bearing reading to a spot on the hill.

2. You then walk perpendicular (right angle) till you reach an off-set of at least 10 Mils. (This example is 20 Mils)
NOTE: The further the landmark, the more distance walked is needed to get a minimum of 10 Mils difference
and the closer the landmark, the less distance walked is needed.

3. Then measure the distance walked from start to finish. (This example is 30 feet or 10 yards)
NOTE: you can use centimeters, meters, feet, yards or any measurement value.

4. Next use the calculation to get the distance to the hill.

5. Use this information to plot your location on the map, using one of the azimuths and distance on your calculation.

ADDITIONAL NAVIGATION SKI LLS
DRAWING A MAP USING THE PREVIOUS SLIDE TECHNIQUES
This technique is good to use when you DO NOT HAVE A MAP and you what to draw a map of the local wilderness area. Here is an example.
1. From your campsite (select landmarks that standout and can be seen) take two bearing readings each; to the Hill, Lake, Tower, and River - one bearing
from the campsite and the other from a perpendicular (right angle) to a measured distance.
2. With the bearing readings calculate the distance from your campsite to each landmark selected. Hill, Lake, Tower, and River.
3. On a sheet of paper draw the camp site as a starting point and Magnetic North on top of the map. With MN there is no need to do any GN conversions.
4. With a protractor covering the campsite and using the campsite bearings, draw light tick marks on the paper at the edge of the protractor bearing.
5. With the Lensatic Compass on the paper, measure from the campsite, thru the bearing, to a determined distance for each landmark and draw the
landmark at the measured distance.
NOTE: When using the Lensatic Compass Graduated Straight Edge, decide which measurement scale you want to use… it can be any value.
6. Add trees and any other information to the map.
When finished, you will have a useful map
to explore and navigate the local area.

CONSERVE ENERGY – REST BREAKS
All groups need to take regular rest breaks in order to hike effectively throughout the day.

• A good schedule is about 5 minutes of rest for every hour of hiking, which will minimize lactic acid buildup
in the body.

• Lactic acid is the by-product created when your muscles burn glucose while you exercise, it’s what
causes your muscles to feel sore.

• When you stop, lactic acid continues to be produced and remains in the system.

• If you stop for less than 5 minutes, this buildup is not a problem.

• If you stop for more than 5 minutes, you may begin to feel muscle soreness and tightening.

• In that case it is best to extend the stop to 25 minutes to allow the excess lactic acid to be cleared out of
your system.
Lactic Acid during REST BREAK
Less than 5 minutes – no problem
More than 5 minutes – muscle soreness and tightening
25 minutes or more – body clears the lactic acid

• Encourage everyone to re-hydrate at every break.


CONSERVE ENERGY – RYTHMIC BREATHING

• Keeping a breathing rate and pattern is one of the best ways to monitor and control your energy output
while hiking.

• RYTHMIC BREATHING - you should move at a pace that allows you to breathe comfortably and be able
to speak.

• If you are constantly gasping for breath or if you can’t keep up a conversation, then you are hiking too fast
for your conditioning level.

• The best way to control your pace is to synchronize the rhythm of your walking (REST STEP) with the
rhythm of your breathing.

• As the hiking load increases from steep terrain, humid weather, or a heavier pack, your breathing rate will
increase.

 Slow your pace to regain that controlled breathing rate.

 When the load is reduced, you can pick up your pace again.

• This technique, when used with the REST STEP (next slide), will maintain a high endurance output over a
long period of time.


CONSERVE ENERGY – THE REST STEP
The mountaineer's ―REST STEP" is your greatest ally on steep ascents. With every step, you briefly transfer weight from your
leg muscles to the skeletal system. It takes a bit of practice, but if done correctly allows you to climb farther without excessive
tiring. Here is how it works:

Step forward with your right leg while keeping your weight on your back (left) leg and momentarily "locking" the back leg in a
straight position. Pause for a split second on your locked left leg. This allows your bones, rather than your leg muscles, to
support your weight.

Swing your left leg forward to take the next step, while locking and transferring your weight to your right (now the back) leg.
Repeat the process with each step, always putting your weight on your locked rear leg.

It's not really a short rest. Instead it's a pause while sinking into the hip deeply. It's more of a stop motion to the continuous
fluid swing of the leg movement that usually happens. This will also allow
you to breathe more evenly and less heavily.
You can tell if you are doing the REST STEP, if
your step is heavy on the terrain and you aren't
breathing too hard.

You need to get into a steady rhythm of doing that for each step you take.
You may feel like a robot walking slowly up the mountain, but you'll feel much
better when you get there.
The REST STEP should be used in conjunction with rhythmic breathing.
The REST STEP keeps your breathing rate easy.


CONSERVE ENERGY – WALKING STICKS
WHY CARRY A WALKING STICK?

IT WILL HELP YOU KEEP YOUR BALANCE IT WILL REDUCE STRESS ON BACK & LEGS
• Crossing creeks, streams, rivers • Provides extra power & balance going uphill
• Traversing hillsides • Reduces shock on knees, going downhill
• Crossing shale, scree • Takes pressure off back and hips (mainly uphill)
• Carrying heavy loads
• Resting en route OTHER USES
• Center or side pole for a tarp
IT WILL HELP YOU MANEUVER • To prop up your pack
• Crossing downed trees over trails • To lean on when resting
• To break or prevent a fall • Pushing aside spider webs and brush
• Self defense against animals, snakes, etc.

SHOULD YOU USE TWO SKI POLES, ONE SKI POLE, ONE WOODEN STAFF, OR SOMETHING ELSE?
• It boils down to what is your preference, or more specifically, what feels right on the trail.
• Hikers use two snow poles when on snow.
• On the trail hikers use one or two poles.
• It takes some time to get use to walking sticks.
• Experiment using both.
• Do what's comfortable, what ever works for you.


PREVENTING BLISTERS
• Blisters demand attention. If you ignore them, you will pay dearly later.
• Always carry a blister kit, even on day hikes.
• Once you hit the trail, you’ll want to pay particular attention to your feet.
• Blisters happen fast, but they do give you a warning.
• If you feel a hot spot, stop immediately.
• Don’t worry about holding up your hiking partners. A short break to check your feet is far better than
limping around on blisters.
• If you do get a blister, first aid treatment makes it possible to walk on a blister, in varying degrees of
comfort.
BLISTER BUSTING TIPS
• Make sure boots fit properly
• Treat boots with oils
• Wear non-cotton sock liners
• Keep feet dry
• Go easy on walking mileage
• Pay attention, any rubbing or soreness, stop immediately and check for foot problems
• If you get blisters in certain areas of feet, put moleskin over it in advance, prior to starting your walk


Not all of these sayings hold true every time under every circumstance,
but you might be surprised at just how accurate they tend to be.

THE MOON
• If you can see the dark part of the crescent moon, it means 24 to
48 hours of good weather.

• A ring around the moon brings rain. By counting the number of stars contained within the ring, you can
fairly accurately predict how long away the rain will be. Each star represents 24 hours, faint star 12 hours.
• If the moon's face is red, of water she speaks. The red color is due to the presence of dust being pushed
ahead of a low pressure front bringing in moisture.
THE SUN
• rainbow or white band around the sun, look for a drastic change in the weather within 12-24 hours. If the
weather is clear, plan on stormy weather; if the weather is dreary, plan on fair weather to arrive.
• Red Sun: A red sun at dusk or dawn indicates dry weather (fair). Don't confuse a red sky in the
morning with a red sun in the morning. If the sun itself is red and the sky is a normal blue color,
the day will be fair.
• Red Sky: A red sky at night, hikers delight, Red sky at morning, hikers take warning.
RAINBOWS
• Rainbows in the morning to the west indicate approaching rain.
• A rainbow at sunset indicates that the rain is leaving and fair weather is on the way.


ATMOSPHERIC LOW PRESSURE (rain)
• If you find yourself out in a marsh or swamp and the air really
seems to stink more than normal, expect rainy weather.
• Birds and bats have a tendency to fly much lower to the ground
right before a rain due to the ―thinning‖ of the air.
• Smoke hanging low means rain is on the way.
ATMOSPHERIC HIGH PRESSURE (fair)
• Things won't smell quite so strong, fair weather.
• The atmosphere becomes more dense and birds can easily fly at higher altitudes, dry air.
• Smoke rising straight into the air means fair weather.
CLOUDS
• An ability to accurately read cloud formations is invaluable in predicting the weather. For a more detailed
look into this, consult a good book on the weather. Each type of cloud is caused by specific actions in
nature building up to fair weather or rainy weather.
PLANTS
• Pine cones - One of the most reliable of all natural weather indicators are pine cones. In dry weather, pine
cones open out as the scales shrivel up and stand out stiffly. When it is damp, they absorb moisture and
as the scales become flexible again, the cone returns to its normal shape.
• Flowers - flowers bloom in fair weather and close when rain is approaching.
• Grass – dew on the grass, rain will never come to pass. When grass is dry at morning light, look for rain
before the night.
