About this map

Twentymile Butte stands as a prominent landmark in this high-altitude section of the Bruneau Desert, where the landscape is defined by vast plateaus and deep drainages. The 2013 survey shows a sparse network of access routes, primarily Flint Mesa Rd and Bell Rapids Rd, which traverse the open range between Flint Mesa and the gulches to the south.

The boundary between Elmore and Owyhee counties cuts across the southern portion of the map, intersecting the path of Deadman Cr. The drainage patterns here, including Rosevear Gulch and Deer Gulch, demonstrate the erosional forces that have shaped the terrain north of Deadman Flat. This map captures a remote corner of Idaho where geography remains the primary feature, dominated by topographic relief and the seasonal flow of desert creeks.
