1983 Map of Mt. Thompson

About this map

Aspendell sits at the northern edge of this high-altitude landscape, serving as a gateway for the recreation and resource extraction that defined the region in the late 20th century. The high basins of the Inyo National Forest are dominated by glacial lakes and towering peaks, with significant water bodies like Lake Sabrina and South Lake serving as landmarks within the John Muir Wilderness. The eastern slopes show evidence of mining history through sites such as the Schober Mine and Salty Peterson Mine, alongside several mineral prospects. This map details the intersection of the Inyo Co and Fresno Co line, where the crest of the Sierra Nevada separates the forest from Kings Canyon National Park. The concentration of campgrounds, including Bishop Park Campground and Four Jeffrey Campground, illustrates the area's transition into a major center for mountain tourism and backcountry exploration.
