About this map

Twentymile Butte stands as a prominent landmark in this high-desert landscape situated along the boundary of Elmore and Owyhee Counties. The terrain is defined by dramatic changes in elevation, from the level expanse of Deadman Flat to the rising edges of Flint Mesa. This 2020 survey illustrates a sparsely settled but surveyed territory, where the vastness of the Bruneau Desert is segmented only by the occasional gulch and seasonal drainage.

A network of remote roads, including Glenns Ferry Castleford Rd and E Flint Mesa Rd, provides access through this arid environment. Water is a scarce resource here, represented primarily by the winding course of Deadman Cr. The map's detailed topography reveals how drainage patterns like Rosevear Gulch and Deer Gulch have carved their way through the mesas, offering a clear record of the region's physical geography.
