2021 Map of Poison Lake

USGS Topo · Published 2021

About this map

Lassen National Forest terrain dominates this survey of the high plateau region in northern California. The landscape is defined by volcanic features and seasonally shifting water bodies, including the prominent Poison Lake and Poison Butte at the center of the sheet. Modern infrastructure is represented by Ca 44, which cuts through the southern half of the quadrangle near the Grays Flat area and Robbers Spring. The map reveals a network of forest service roads like Pittville Rd and Lodgepole, which provide access to more remote locations such as Patterson Flat and the cinder cones of Cone Mtn and Cal Mtn. The presence of Coyote Hale and several named reservoirs and lakes, such as Half Cabin Reservoir and Ebey Lake, underscores the importance of water management and livestock grazing in this timberland and volcanic basin environment.
