About this map

Mahogany Mountain and the Owyhee River dominate this high-desert landscape along the Oregon-Idaho border as it appeared in the early 1980s. The terrain is defined by dramatic geology, from the deep incisions of Leslie Gulch and Blue Canyon to the extensive volcanic fields of the Jordan Craters Research Natural Area. Sparse human settlements such as Crowley and Sheaville are scattered across the map, connected by primitive roads that navigate through the Owyhee Breaks and across Bogus Bench.

Water management is central to life in this arid region, evidenced by numerous named flats and reservoirs, including Big Mud Flat, Littlefield Reservoir, and Ben Odell Reservoir. Unique landmarks like The Hole in the Ground and Skull Spring provide specific points of reference for local history and land use. The map captures the transition between the volcanic Lava Field in the south and the high ridges like McIntyre Ridge and Purser Ridge to the east.
