The high backcountry of the Blue Mountains defines this 2017 survey, where the border between Umatilla and Wallowa counties follows the natural drainage divides of the Umatilla National Forest. The landscape is dominated by complex ridgelines such as Paradise Ridge and Broken Ridge, which separate the headwaters of the S Fork Walla Walla River from the S Fork Wenaha River. A network of forest management roads and historic paths, including the Kendall Skyline Rd and the Shoofly Trail, provide the primary access through this steep terrain. Named water sources like Buckskin Spring, Bear Trap Spring, and the namesake Bone Spring serve as critical landmarks for navigation and resource management in this high-elevation wilderness.
