1982 Map of Mt. Abbot

USGS Topo · Published 1994

About this map

John Muir Wilderness and the high ridges of the Sierra National Forest dominate this 1982 survey of the central Sierra crest. The landscape is defined by the sharp convergence of Fresno, Mono, and Inyo counties at massive granite summits like Mt Abbot and Mt Mills. High-altitude passes such as Mono Pass and Gabbot Pass provided the only practical traverse across the Mono Divide for early mountaineers and surveyors. The drainage patterns show Mono Creek winding through the recesses of the western slope, while the eastern side drops into the glacial carved Rock Creek Valley. The map details the network of alpine lakes, including the sprawling Pioneer Basin and the cluster of Treasure Lakes, reflecting a wilderness era preserved for recreation. This topography shows the John Muir Trail as it negotiates the high country before late-century management changes altered the local back-country access.
