The Aldrich Mountains dominate the southern half of this landscape within the Malheur National Forest, where steep drainages and high ridges converge. The northern portion of the map is defined by the east-flowing John Day River, which is paralleled by the highway and fed by numerous seasonal and perennial streams including Fields Creek and Widows Creek. The presence of the Eddington Ditch near the river indicates the historic and ongoing management of water resources in this arid Grant County environment. The terrain rises sharply from the river valley toward prominent summits such as Coyote Butte and Horseshoe Butte. Along the southern boundary, Chrome Ridge and Big Canyon mark the transition into deeper forest land, while scattered springs like Lick Spring provide vital water points in the higher elevations. This map captures the intersection of early forest service road networks, like Fields Creek Rd, and the natural corridors that have shaped local transit for generations.
