2021 Map of Mount Lyell

USGS Topo · Published 2021

About this map

Mt Lyell and the surrounding peaks of the Cathedral Range dominate this high-altitude landscape where the boundaries of Tuolumne, Mono, and Madera counties converge. The drainage of the Merced Wild and Scenic River and its tributary, the Lyell Fork Merced River, create a complex network of glacial basins and alpine lakes, including Florence Lake and the cluster of Isberg Lakes. High-country travel is represented by historic routes like the Isberg Pass Trl crossing the Sierra Nevada, connecting remote sections of Yosemite National Park with the Sierra National Forest. The map documents a strictly wilderness environment, lacking permanent settlements or roads, instead focusing on natural landmarks such as Rodgers Peak and Triple Divide Peak that define the crest of the range.
