About this map

Peabody Homestead and several isolated ranching outposts define the human footprint on this high-desert landscape in central Harney County. The Silvies River meanders across the northern reaches of the sheet, providing a vital water source for cattle operations such as Dixon Ranch and Whiting Ranch. The terrain is characterized by broad upland features like Gravel Ridge and Mahogany Ridge, which overlook the seasonal drainages of Dry Creek and Poison Creek.

Remote infrastructure is centered around high-elevation landmarks like Cow Camp and Mosquito Flat. These locations, along with numerous named water sources including Bob Bennett Spring and Rimrock Spring, highlight the region's historical dependence on spring-fed grazing lands. The map traces the rugged path of Gravel Ridge Way and Poison Creek Rd, which served as the primary transit corridors for these high-country homesteads and grazing allotments during the early 21st century.
