Clear Lake National Wildlife Refuge anchors the southern portion of this high-desert landscape on the border of California and Oregon. The terrain is defined by the expansive Clear Lake Reservoir, a critical water source and habitat area that transitions into the protected acreage of the Modoc National Forest. This modern survey reveals a network of water features essential to the region's ecology and history, from the Mammoth Springs to the winding course of the Lost River.
