1992 Map of Mount Lyell

USGS Topo · Published 1995

About this map

Mount Lyell and the Cathedral Range dominate this high-altitude landscape where three major wilderness areas and national forests meet. Surveyed in the early 1990s, the map reveals a complex glacial environment at the headwaters of the Merced River. The presence of the Lyell Glacier and Maclure Glacier highlights the era’s alpine topography before significant late-20th-century recession. Access is limited to the winding Pack Trail system, which connects remote water bodies like Washburn Lake and Florence Lake to high passes. This intersection of the Yosemite Wilderness and Ansel Adams Wilderness showcases the untouched granite peaks and alpine lakes that define the crest of the Sierra Nevada, providing a record of the backcountry as it existed just before the turn of the millennium.
