The Ritter Range dominates this landscape, serving as a divide between the high alpine basins and the deep river valleys of the Sierra Nevada. This 2021 survey illustrates a complex network of glacial lakes and seasonal watercourses, including Gertrude Lake, Ashley Lake, and Anona Lake nestled in the north. The southern reaches are defined by the convergence of major waterways, where the N Fork San Joaquin River and Middle Fork San Joaquin River meet near Junction Butte.
