About this map

Ochogo National Forest dominates this section of Harney County, characterized by a complex network of springs and drainages that sustain the high desert landscape. The terrain is defined by prominent elevations such as Donnelly Butte and long features like Howard Ridge and Dodson Ridge. These ridges overlook substantial open spaces including Duffy Prairie and Boone Prairie, which are essential features for understanding the historical grazing and land-use patterns of the region.

The abundance of named water sources, from Packsaddle Spring and Bixby Spring to Harpham Spring, suggests a landscape where water management was critical for survival and stock raising. Waterways like Mutton Creek, Wickiup Creek, and Silver Creek carve through the topography, connecting the high ridges to the lower basins. This 1990 provisional map provides a detailed view of these natural resources before modern shifts in forest management and environmental changes altered the character of the Harney County backcountry.
