1999 Map of Mosquito Flat

USGS Topo · Published 2002

About this map

Malheur National Forest dominates this high-desert landscape in Harney County, where the topography is defined by the Silvies River and a network of drainages including Poison Creek and Stancliffe Creek. The terrain transitions from the elevations of Gravel Ridge and Mahogany Ridge down toward the open expanse of Mosquito Flat. This 1990s record of the high country highlights the enduring presence of early 20th-century land claims and agricultural outposts. Evidence of ranching history is scattered across the township lines, notably at Whiting Ranch, Groff Ranch, and the Peabody Homestead. Remote working sites like the Cow Camp (Site) reflect the seasonal livestock movements typical of this region, while numerous named springs such as Rimrock Spring and Lone Pine Spring mark critical water sources in the arid Harney Basin environment.
