1901 Map of Mt. Lyell

About this map

Mt Lyell and the high ridges of the central Sierra Nevada are captured here as they appeared during the 1898-99 surveys by R.B. Marshall and H.E.C. Feusier. The landscape is defined by the intersections of Yosemite National Park, Sierra National Forest, and Mono National Forest. Significant glacial features, including the Lyell Glacier and Conness Glacier, crown the peaks, feeding the headwaters of the Merced River and the San Joaquin River. The map illustrates a high-altitude wilderness at the turn of the century, where early administrative markers like the Clover Meadow Ranger Sta and seasonal livestock areas such as Sheep Crossing and Cargyle Meadow hint at the era's grazing and conservation efforts. From the expansive Tuolumne Meadows to the distinct geological formation of the Devil Postpile, the topography reflects a world of early mountaineering and natural resource management before the widespread development of modern recreational infrastructure.
