1966 Map of Summer Lake

About this map

Winter Ridge dominates the western half of this landscape, its steep escarpment dropping sharply toward the vast alkaline basin of Summer Lake. This dramatic geological transition defines the area, with the densely forested slopes of the Fremont National Forest meeting the wetlands of the Summer Lake State Wildlife Area. A notable historic line, the Old Indian Treaty Boundary, cuts diagonally across the ridge, marking a significant division in the land's colonial and indigenous history.
