Name a valley (or “canyon”) other than Bloody Canyon that has glacial steps. How many steps are there? How many lakes are found in the series of steps?
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?
