Malheur National Forest dominates this section of eastern Oregon, where the headwaters of the North Fork Malheur River and the Little Malheur River carve through the high-elevation landscape. The terrain is defined by a dense network of upland springs and small-scale water management features, including isolated pools like Dead Horse Reservoir, Skagway Reservoir, and Slate Reservoir. These features, along with names like Tin Wagon Canyon and Rattlesnake Ridge, point to a legacy of ranching and resource management in the high desert. The map also documents the boundary between Grant and Harney counties, showing how early political lines follow the topographic height of land. Water sources such as Buck Trough Spring and Red Trough Spring appear as critical landmarks for navigation and land use in this remote forest environment.
