2013 Map of Four Corners

About this map

Whitehorse Butte stands as a prominent landmark in this high-desert portion of Owyhee County, surveyed in 2013. The landscape is defined by its arid basins and vital water catchments, including Four Corners Reservoir and Little Juniper Basin Reservoir. The terrain transitions from the Little Horse Basin in the west across the expanse of the Y P Desert, reflecting a remote ranching or grazing environment where water management is central to the land's utility. Local nomenclature like Horse Basin and E Horse Basin Reservoir indicates the historical and ongoing importance of livestock in this corner of Idaho. The map provides a precise look at the drainage patterns and elevation changes across the Four Corners area, illustrating how the natural topography has been utilized for water storage in an otherwise dry climate.
