Umatilla National Forest encompasses the high country of this Grant and Morrow County borderland, where the terrain is carved by a complex network of canyons and creeks. The hydrology of the region is defined by the North Fork John Day River, which winds through the southern portion of the quadrangle. High points like Johnny Cake Mtn and Neal Butte overlook deep drainage systems such as Coyote Canyon and Mulligan Stew Canyon. Named flats, including Mahogany Flat and Gilman Flat, suggest areas of relatively level ground amidst the steep draws. The map identifies critical water sources in this arid landscape, such as Buckhorn Spring and Tonto Spring, which historically supported movement through these uplands. Forest roads like Nat For Dev Rd 22 and Wall Cr Rd provide the primary access to these remote canyons and timberlands.
