The Columbia River defines this stretch of the Pacific Northwest, where the waters of Lake Umatilla separate Washington and Oregon. Much of the northern shoreline is dominated by the Umatilla National Wildlife Refuge, protecting riparian habitats around Crow Butte and Whitcomb Island. The landscape is a study in agricultural and military land use; large-scale circles of irrigated farmland, such as those reached by 100 Circle Farms Rd, sit adjacent to the sprawling Naval Weapons Systems Training Facility Boardman. Transport and infrastructure are vital to the area's character, evidenced by the West Extension Irrigation Canal and the Boardman Airport located south of the river. The terrain transitions from the river valley into geological features like Canoe Ridge and Artesian Coulee, reflecting a region defined by water management and federal land stewardship.
