About this map

The high plateau and volcanic ridges of the Modoc National Forest dominate this landscape along the border of Modoc and Lassen counties. Knox Mountain serves as the central topographic anchor, with its slopes draining into Cottonwood Creek and Hilton Creek. The presence of the Old Likely Mill (Site) provides a specific point of interest for industrial history, marking a location where timber or grain processing once shaped the local economy.

Settlement is sparse, characterized by isolated outposts such as Hilton and the Comfort Cabin Springs. Water sources are critical in this high-elevation terrain, as evidenced by the numerous named springs including Yellowjacket Spring, Salt Log Spring, and Indian Springs. The map also captures the transition from timbered heights to the open flats of Rocky Prairie and Knox Flat, showing the network of 4WD trails that connect these remote ranching and forest management sites.
