1983 Map of Mt. Henry

USGS Topo · Published 1987

About this map

The South Fork San Joaquin River winds through the high Sierra Nevada landscape of Fresno County, forming a deep central drainage flanked by the John Muir Wilderness and Kings Canyon National Park. This 1983 survey records a pristine wilderness environment where the John Muir Trail and Pacific Crest National Scenic Trail intersect, highlighting the region's importance to early 20th-century conservation and mountaineering. The presence of the John Muir Trail Cabin and named sites like Reddys Hole indicate the light but permanent mark of trail development in these high elevations. Moving south from Pavilion Dome toward the Red Mountain Basin, the map details a complex glacial geography characterized by the Matthes Glaciers and high-altitude crossings such as Hell for Sure Pass and Mosquito Pass.
