1983 Map of Mt. Henry

About this map

High Sierra wilderness topography is meticulously documented in this 1983 study, centered on the meeting of the Sierra National Forest, John Muir Wilderness, and Kings Canyon National Park. The landscape is dominated by the South Fork San Joaquin River and its major tributaries, including Evolution Creek which flows through the notable Evolution Valley. For researchers and historians of alpine recreation, the map shows the iconic Pacific Crest National Scenic Trail and the John Muir Trail as they traverse the Glacier Divide. A rare architectural landmark, the John Muir Trail Cabin, is located near the river's fork, while more ephemeral features like Shooting Star Meadow and a marked Campsite indicate the area's use by backpackers. The terrain varies from the depths of Reddys Hole to the heights of Mt Henry and Emerald Peak, tracing a network of high-altitude basins like the lake-studded Red Mountain Basin.
