1953 Map of Mt. Morrison

About this map

Inyo National Forest dominates this mid-century survey, revealing a landscape defined by its geothermal activity and mining history. Several hot springs, including Casa Diablo Hot Sprs and Whitmore Hot Springs, dot the valley floors while the high peaks of the Sierra Nevada rise to the west. The settlement of Mammoth Lakes is shown alongside legacy mining sites like the Old Mammoth Mine and the Mammoth Consolidated Mine. High-altitude water bodies such as Convict Lake and Lake Mary provide a drainage network toward Crowley Lake, which serves as a major landmark on the eastern edge of the quadrangle. Early infrastructure is documented through the Mammoth Ranger Sta, St Joseph Ch, and the Fish and Game Experimental Sta near Convict Creek. The mapping also traces the Muir Trail as it winds through the southern peaks near Red Slate Mtn and Duck Lake.
