The document summarizes geological investigations of the Mono Basin and surrounding area using ArcGIS. It describes three main tasks: 1) investigating correlations between faults and springs; 2) charting shoreline development over time; and 3) using hyperspectral imaging to study the Mono Craters. ArcGIS was used to map faults, springs, and shorelines to analyze their relationships and identify potential geothermal sites. Hyperspectral data from the AVIRIS sensor was analyzed to identify mineral compositions and study the Mono Craters.
