Glaciation in upland areas has created landforms like corries, arêtes, and pyramidal peaks through freeze-thaw weathering and erosion by glaciers. Glaciers carved out U-shaped valleys and left behind landforms like hanging valleys, truncated spurs, and ribbon lakes. Glacial deposition formed features such as drumlins, moraines, and boulder clay. Upland glaciated areas are used for marginal farming, forestry, and tourism, but management is needed to address issues from overuse, like erosion, and conflicts between different user groups.
