Drumhill Ridge forms the high spine of this terrain in the mid-1990s, marking a rugged boundary between the Umatilla National Forest and the Wallowa-Whitman National Forest. This survey documents a landscape of essential forest infrastructure and historical trail markers, including the Summit Guard Station and established campsites like Camp One and Camp Three. The eastern edge is defined by the steep descents toward Emily Creek and Five Points Creek, while the western slopes drop toward the headwaters of Wilbur Creek.
