About this map

Modoc National Forest occupies the majority of this high-plateau landscape, characterized by isolated peaks like Donica Mountain and Splawn Mountain rising above broad flats. The terrain is marked by a complex system of water management and natural springs, including the Joiner Reservoir, Upper Roberts Reservoir, and Hines Reservoir, alongside numerous watering points such as Armentrout Spring and Loody Springs. These features, combined with the presence of Armentrout Flat, suggest a landscape shaped by seasonal grazing and remote forest operations within the public lands.

Transport and utility are defined by the presence of Lookout Junction and Lookout Siding in the southwestern corner, reflecting the importance of rail and road connections to the more developed areas of the Big Valley River and Pit River basins. Sparse human habitation is evidenced by the remote Roberts Camp, while land use is further indicated by local industrial sites like the Barrow Pit and Gravel Pit.
