About this map

Umatilla National Forest defines the southwestern portion of this landscape, where the terrain breaks into a complex network of ridges and deep drainage canyons. The map documents a rugged corner of Asotin County where the high ground of Harlow Ridge, Smiley Ridge, and Bennett Ridge separates the watersheds of South Fork Asotin Creek and George Creek. This 2023 survey illustrates the remote character of the region, emphasizing natural water sources such as Park Spring, Petty Spring, and Vogan Spring that are critical in this high-elevation environment.

Transportation is primarily restricted to established ridgeline routes like Smoothing Iron Rd and the Asotin - Cloverland Road. The presence of the Hawks Run Airport in the northeast corner suggests the continued importance of aerial access in this isolated territory. For those tracing the geography of the Blue Mountains' eastern fringes, the map provides detailed placement of named landforms such as Little Butte and Triple Ridge.
