The agricultural landscape of Umatilla County is anchored here by the settlement of Adams, situated along the winding course of Wildhorse Creek. This region of the Columbia Plateau is defined by a series of distinct drainages, including Greasewood Creek and Spring Hollow Creek, which carve through the high ground. The map reflects a rural economy dependent on well-distributed transit, shown through an extensive grid of named county roads such as Sand Hollow Rd and Gerking Flat Rd that connect isolated homesteads and farmland.
