What is the name for the kind of glacial landform marked by the black dashed line halfway between Mt. Dana and Mt. Gibbs? How did it form?
The question is based on Map T-13, the “Mono Craters, California” quadrangle (scale 1:62,500; contour interval 80 feet), and Figures 48-5 and 48-7, a detailed map and stereogram, and Map T-23a, a satellite image, of the same region. The heavily glaciated eastern crest of the Sierra Nevada is seen along the western sides of the map and stereograms (37°52'37"N, 119°12'40"W). During the Pleistocene, glaciers in this region flowed down the valleys of the eastern slope of the Sierra toward the Mono Lake basin to the northeast. Large lateral moraines are found at the mouths of each canyon. What will be an ideal response?
