2017 Map of Mosquito Flat

About this map

The Malheur National Forest dominates this section of Harney County, Oregon, where the headwaters of the Silvies River and Poison Cr cut through high plateau terrain. This landscape is defined by its numerous isolated water sources, including Bob Bennett Spring, Rimrock Spring, and Peabody Spring, which provided essential stopping points for livestock and travelers in an arid high-desert environment. The namesake Mosquito Flat sits in the southwest corner, while the eastern edge is marked by dramatic elevation changes in Heifer Canyon and Devine Canyon. Forestry and grazing infrastructure are evidenced by an extensive network of service roads, including Lost Creek Rd and Gravel Ridge Way, which navigate between prominent landforms like Mahogany Ridge and Gravel Ridge.
