1951 Map of Clear Lake Reservoir

About this map

Modoc National Forest dominates this northern California landscape, centered on the expansive waters of the Clear Lake Reservoir. Established as the Clear Lake National Wildlife Refuge, the area preserves a rugged volcanic terrain marked by natural formations like the Mowitz Rock Wall and prominent peaks including Double Head Mtn and Carr Butte. In the mid-twentieth century, the region remained largely dedicated to ranching and timber, with isolated outposts such as McNeil Ranch and Holbrook Ranch serving as focal points for local land use.
