2023 Map of Twentymile Butte

USGS Topo · Published 2023

About this map

Bruneau Desert dominates this high-altitude landscape along the border of Elmore and Owyhee counties. The terrain is defined by deep incisions and high overlooks, notably Twentymile Butte and the broad Flint Mesa to the north. A network of unpaved roads, including E Flint Mesa Rd and Glenns Ferry Castleford Rd, provides the primary access through this dry expanse, connecting remote grazing or transit points. To the west, the land levels out slightly at Deadman Flat before dropping into the drainage of Deadman Creek. The map documents a sparsely populated but distinctly named geography where erosion has carved features like Rosevear Gulch and Big Pilgrim Gulch, illustrating the isolated character of this high desert region in the modern era.
