2013 Map of Diamond Peak

About this map

The Umatilla National Forest landscape across the Columbia and Garfield county line reveals a high-elevation backcountry marked by isolated camps and family holdings. At the southern edge of the quadrangle, the F Kessler Ranch, C H Neal Ranch, and J R Evans Ranch represent the high-country ranching tradition near Grouse Flat, where Kessler Mill Rd provides the primary access. Further north, the terrain transitions into a series of dramatic ridges and peaks including Mt Misery, Diamond Peak, and Halsey Butte. The map illustrates a network of essential water sources for livestock and wildlife, from Sheephead Spring near Sheephead Corral to Pistol Spring and Fairview Spring tucked along Smooth Ridge. This territory, defined by its steep drainage systems like Slide Canyon, remains largely defined by the forest service and ranching operations.
