2018 Map of Copic

About this map

The high desert topography of Modoc County is anchored here by the tiny settlement of Copic and the nearby community of Cornell. This 2018 survey documents a landscape defined by volcanic landforms and seasonal water management within the Modoc National Forest. Named islands, including Snake Island, Lands Island, and Stone Island, suggest the historical presence of more extensive surface water in this arid basin, now punctuated by the Mason Reservoir and Harvey Lake. The terrain is characterized by prominent elevations such as Casuse Mtn, Coyote Butte, and Tucker Butte, which overlook broad flats like Dobie Flat and Saddle Blanket Flat. A complex network of county roads, including Co Rd 135 and Co Rd 169, provides access to these remote reaches, while specialized spurs like Tucker Butte Spur and Harvey Lake Spur serve the forest's interior.
