About this map

Lake Almanor and the surrounding timberlands of the Lassen National Forest define this 1970s landscape in Plumas County. The map details a sophisticated hydroelectric system, tracing a tunnel and penstock from the lake down to a powerhouse at the head of Butt Valley Reservoir. Small settlements like Prattville and Almanor sit along the southwestern shore, while historic transportation routes like Humboldt Road and Humbug Road cut through the heavy forest cover.

Evidence of the region's diverse history is scattered across the terrain, from the legacy of ranching at Keefer Ranch to small-scale extraction at the Mule Shoe Mine. The boundary between the Lassen and Plumas National Forest runs through the center of the sheet, where various recreational sites like Ponderosa Flat Campground and Cool Springs Campground are situated to take advantage of the reservoir's shoreline.
