The Columbia River serves as the dominant artery in this 1941 tactical survey, separating the shores of Washington and Oregon. Along the southern banks, the city of Clatskanie is a hub for the surrounding timber and agricultural uplands. A dense network of rural infrastructure is visible, including the Crossing Cem and a string of local education centers like Quincy School, Lacoda School, and Alder Grove School. The river landscape is characterized by complex waterways such as Bradbury Slough and Fishers Channel, which navigate around Crims Island and Fisher Island.
