1990 Map of Chalk Mountain

USGS Topo · Published 1990

About this map

The Pit River carves a deep path through the northern reaches of the Shasta National Forest, where industrial utility and remote wilderness meet. This 1990 provisional map documents the hydroelectric infrastructure of the era, including the Pit 5 Dam and Pit 4 Dam, supported by an adjacent Powerhouse, Substation, and Surge tank. The landscape is defined by its significant relief, rising from the Pit 4 Reservoir to the heights of Chalk Mountain and Hatchet Mountain.
