1990 Map of Ten Lakes

USGS Topo · Published 1990

About this map

The Grand Canyon of the Tuolumne River carves a dramatic path through this high-altitude landscape within Yosemite National Park. Surveyed in the late 1980s, the map documents the intricate river-and-trail system of the Yosemite Wilderness, including the exact river mileage for points like Pate Valley and Muir Gorge. The topography is defined by significant granite peaks such as Colby Mountain and Grand Mountain, punctuated by alpine water systems including the Ten Lakes basin and Grant Lakes. Interpretive details reveal the high-country meadow systems, from Pleasant Valley in the north to Halfmoon Meadow and Rodgers Meadow, which have long served as critical nodes for navigation. The map also delineates the administrative boundary where Tuolumne County meets Mariposa County along the southern drainage of Yosemite Creek.
