1901 Map of Mt. Lyell

USGS Topo · Published 1950

About this map

The High Sierra at the turn of the century is captured in this 1898-99 survey, showing the overlaps of early conservation and rugged alpine terrain. Yosemite National Park occupies the western portion of the sheet, while the Sierra Forest Reserve and the newly designated Devils Postpile National Monument define the southern and eastern landscape. The survey details the glacial topography around Mt. Lyell and Mt. Dana, noting the intricate network of alpine lakes such as Thousand Island Lake and Garnet Lake that feed the upper reaches of the San Joaquin and Tuolumne rivers. Further east, the descent toward Mono Lake is marked by steep canyons and prominent peaks like Mt. Conness. Human infrastructure is sparse, represented by the Clover Meadow Ranger Sta and early mountain passages including Tioga Pass and Donohue Pass.
