1987 Map of Patterson Mtn

About this map

Patterson Mountain and the steep river canyons of the Sierra National Forest define this high-elevation landscape in the late 1980s. The map centers on the sophisticated hydroelectric and water management systems along the Kings River, including the Haas Powerhouse and the Black Rock Reservoir. This area demonstrates a heavy investment in industrial infrastructure within a wilderness setting, evidenced by the Balch Powerhouse Substation and several Gaging Stations positioned along the tributaries. The Teakettle Experimental Area occupies the north-central portion of the quadrangle, highlighting the region's importance for forest research. Below the prominent Patterson Bluffs, the settlement of Balch Camp serves as a small human footprint amid vast natural features like Rodgers Ridge and Poison Ridge.
