Oak Point and the surrounding riverfront of the Columbia River anchor this 2017 survey, where the waterway defines the borders between Cowlitz and Columbia counties. The landscape is a network of complex aquatic features, including Crims Island, Gull Island, and the winding Eureka Channel. These islands and sloughs, such as Dobbins Slough and Rousky Slough, illustrate the heavy fluvial influence on local land use and boundaries.
