About this map

Pit River hydro-electric infrastructure dominates this mountainous Shasta County landscape, where the Powerhouse and its associated Substation, Penstocks, and Surge Tank utilize the dramatic elevation changes of the canyon. The 1990s terrain is marked by significant water management features including Pit 5 Dam and Pit 4 Dam, which regulate the river's flow as it carves between Chalk Mountain and Bales Mountain.

Transitioning into the higher elevations of the Shasta Trinity National Forests and Lassen National Forest, the map reveals a network of natural and recreational sites. High-altitude water bodies like Lake Margaret and the Haynes Reservoir 2223 Dam sit near Bunchgrass Mountain. Evidence of human presence remains localized at Hagen Flat and Oak Flat, while Bunchgrass Road provides access through the heavy timber and across the ridges of Hatchet Mountain.
