1982 Map of Balloon Dome

About this map

The San Joaquin River carves a dramatic path through this high-altitude landscape of the early 1980s, where the prominent Balloon Dome stands as a massive landmark overlooking the river valley. The map details the remote reaches of the Sierra National Forest and the southern edge of the John Muir Wilderness, highlighting a wilderness infrastructure that supported forest management and early recreation. Crucial access points like the Cassidy Bridge and Lower Miller Crossing provided the only crossings for travelers navigating the waterways that divide Madera Co and Fresno Co.
