Burnt Lava Flow Geological Area dominates the northwestern corner of this territory, where volcanic history is etched into the landscape along the Siskiyou and Modoc County border. This high-altitude terrain is defined by its conservation and management history, split between the Modoc National Forest and the expansive Modoc State Game Refuge. High points like Border Mountain and Buck Butte overlook a network of Forest Service roads, including 42n25 and 42n03, which connect remote resources like the Cinder Pit and various corrals.
