About this map

Harper Basin and the surrounding high ridges define this Malheur County landscape as it appeared in the early 1970s. The topography is dominated by massive north-south formations including Hoodoo Ridge, Keeney Ridge, and Freezout Mountain. This is a terrain of essential water management for ranching, evidenced by a dense network of springs and named reservoirs such as Hog Leg Reservoir, Slim and Fatty Reservoir, and the uniquely titled Hood of Hoodoo Res.

Remote infrastructure is sparse, limited to the isolated Winter Camp and the curious Sage Hen Pen located near Harper Basin Spring. These features, connected by a web of trails and jeep trails, reflect a specialized land use focused on livestock and seasonal range management. The presence of numerous small-scale catchments like Stacey Res No 1 and Conway Reservoir underscores the vital role of water engineering in this arid Oregon high country.
