About this map

Ochoco National Forest defines this high-desert landscape in Harney County, characterized by a series of volcanic-named ridges and seasonal drainages. The area is anchored by Donnelly Butte and expansive grassy openings like Duffy Prairie and Boone Prairie, which traditionally served as vital grazing grounds in the Oregon backcountry. Water sources are critical here, evidenced by the high concentration of named springs including Salt Canyon Spring, Wickup Spring, and Bear Wallow Spring.

The map reveals a complex system of deep cuts, such as Mineral Canyon and Salt Canyon, which channel water toward the southern reaches of the forest via Wickup Cr and Claw Cr. Access to these interior reaches is largely provided by Howard Ridge Rd, tracing the spine of Howard Ridge. This survey documents a quiet but essential corner of the Pacific Northwest's public lands, where topography and hydrology dictate the use of the land for ranching and forest management.
