1999 Map of Clevenger Butte

About this map

The Malheur River and its tributary, the Little Malheur River, define the hydrology of this high-desert terrain along the boundary of the Malheur National Forest. This 1990s revision reveals a landscape primarily dedicated to grazing and forest management, where the confluence of numerous drainages such as Bridge Creek and Lost Creek carved the canyons below Clevenger Butte. Human presence is sparse but specific, marked by working sites like The Holdout Cow Camp and the river passage at Lockhart Crossing. The topography is dominated by distinct volcanic and erosion-formed peaks, including Ring Butte, Sheep Rock, and Iron Mountain. Extensive 4WD trails crisscross the ridges, tracing the lines of forest access and ranching activity between the borders of Grant and Malheur counties.
