1966 Map of Summer Lake

About this map

Winter Ridge dominates the western landscape of this Lake County survey, creating a sharp escarpment that drops toward the marshlands and alkaline waters of Summer Lake. The 1966 field check records a delicate balance between the high timber of the Fremont National Forest and the wetland ecosystems of the Summer Lake State Wildlife Area. Cultural markers of early settlement are preserved in the topography, including the Old Indian Treaty Boundary cutting across the forest floor and the Ana River Sch near the small community of Summer Lake. The hydrology of the basin is well-documented, showing the flow from Ana Reservoir feeding the Ana River, alongside numerous springs like Bagley Spring and Bottle Spring that emerge from the base of the ridge. A local Grange Hall and the Headquarters for the wildlife area stand as central landmarks for this rural high-desert outpost.
