1992 Map of Twentymile Butte

USGS Topo · Published 1992

About this map

The historical Oregon Trail cuts across this high desert landscape, tracing a path through the northern reaches of the quadrangle. The map captures a transition between the elevated Flint Mesa and the wide expanse of Deadman Flat, a region defined by its complex drainage systems including Rosevear Gulch and Deadman Creek. The interior is crisscrossed by essential ranching and transit infrastructure, such as the Bell Rapids Road and a solitary Water Tank, reflecting the area's agricultural and logistical importance at the boundary of Elmore and Owyhee counties. The namesake Twentymile Butte stands as a prominent navigational landmark overlooking the deep gulches and arid plateaus that characterize this southern Idaho territory in the early 1990s.
