About this map

The Modoc National Forest dominates this northern California landscape, defined by a mix of high-altitude basins and specialized infrastructure as it appeared in the early 1990s. A significant portion of the terrain is occupied by the OTHB Radar Installation, a Cold War-era Over-the-Horizon Backscatter facility enclosed by a Military Reservation Boundary. This specialized installation reflects the region's strategic importance during the late twentieth century, situated amidst a network of natural and improved water sources.

Water management in this arid timberland is evident through features like Rimrock Lake, Double Head Lake, and the remote Flukey Well. Smaller settlements and seasonal sites like Horse Camp and named clearings such as Bob Young Flat provide specific points of interest for local historians and land use researchers. The map also captures the transition between forest and private lands, with various unimproved roads and trails connecting Lone Pine Lake and Cummins Lake across the Modoc County high country.
