2021 Map of Steele Swamp

About this map

The California-Oregon border cuts across this high-desert landscape where the Fremont National Forest meets the Modoc National Forest. The map is centered on a series of basins and drainages, most notably Steele Swamp and the high-altitude Dog Lake. This area was historically traversed by the Old State Line road, which skirts the northern edge of Fourmile Valley. The terrain is defined by volcanic features and hydrologic markers like Bird Spring Ridge and Fourmile Reservoir. Water sources are critical in this environment, with Fort Spring and Warm Spring providing reliable points of reference for land management and early travelers between Klamath and Modoc counties. The detailed mapping of Willow Cr and Rock Creek illustrates the complex drainage patterns feeding into the larger swamp systems.
