Lake Wallula dominates this borderlands topography, where the Columbia River forms the divide between Benton County, Washington, and Umatilla County, Oregon. This early 1990s survey illustrates a landscape of deeply incised drainages, including Swaler Canyon, Spaw Canyon, and the extensive Cold Springs Canyon in the south. The settlement at Juniper sits near the river's edge, while the inland areas are marked by infrastructure such as a Landing Strip, a Pipeline, and various substations. Local travel and access are defined by a network of unimproved roads and four-wheel-drive trails, alongside named routes like Kosmos Road and East Walls Road. The presence of a Sand Station Recreation Area and various gravel pits suggests a mix of public use and local resource extraction in this arid riverine environment.
