1989 Map of Lake Almanor

About this map

The massive expanse of Lake Almanor dominates this 1980s landscape, serving as a hub for both industry and recreation in the High Sierra. The map details the developed shorelines near Chester and Hamilton Branch, while tracing the critical water management systems of the Butt Valley Reservoir and the North Fork Feather River. To the west, the volcanic topography rises toward the iconic Lassen Peak and Brokeoff Mountain within Lassen Volcanic National Park. The survey illustrates a complex geography of land use, from the timber-rich reaches of the Lassen National Forest to the specialized preservation of the Ishi Wilderness. Smaller mountain communities like Mineral and Butte Meadows are connected by a network of state routes, while the Union Pacific line maintains its path through the rugged canyon country to the south near Belden.
