About this map

Lake Almanor and the northern reaches of the Butt Valley Reservoir dominate this mid-1990s survey of the High Sierra landscape. The settlement of Prattville sits along the shoreline, serving as a focal point near the Almanor Peninsula. The map reveals a complex infrastructure of water management and power generation, including the Butt Valley Tunnel, a Surge Chamber, and a Powerhouse located at the northern tip of the lower reservoir.

Further south, Humbug Valley provides a glimpse into the region's ranching and early transit history, marked by the presence of Keefer Ranch and the historical Humboldt Road. Small settlements like Longville and the localized Cem reflect the sparse but persistent human footprint within the Lassen National Forest and Plumas National Forest. Industrial activity is noted at the Mule Shoe Mine and various pits, while the topography rises toward Mt Hough Almanor.
