2020 Map of Four Corners

About this map

Whitehorse Butte stands as a prominent landmark in this high-desert portion of Owyhee County, where the landscape is defined by its wide basins and seasonal water management. The area around Four Corners features a network of strategically placed water sources, including the Four Corners Reservoir and Little Juniper Basin Reservoir, which highlight the necessity of water infrastructure in this arid region. The topography transitions from the open stretches of the Y P Desert into the distinct depressions of Horse Basin and Little Horse Basin. This 2020 survey documents the modern layout of these remote rangelands, showing the intersection of several townships including t15s r2w and t16s r1w. The map provides a clear look at the sparse road network and hydraulic features like the East Horse Basin Reservoir that support land use in this isolated part of Idaho.
