Imnaha River drainage and the surrounding mountain ridges define this 2014 survey of the Wallowa National Forest. The geography is marked by a complex system of watercourses and canyons, including Pileup Canyon and Crooked Canyon in the southeastern quadrant. Higher elevations are anchored by prominent landmarks such as Grizzly Ridge and Haas Ridge, while the namesake Haas Hollow sits below the ridge line. Human presence is largely represented by a network of forest roads and trails, including Rimrock Rd, Lower Imnaha Rd, and Fence Line Creek Rd. The abundance of named springs and creek forks, such as Pucksaddle Spring and S Fork Chesnimnus Cr, highlights the vital hydrology of this high-elevation landscape within Wallowa County.
