The Columbia River dominates this landscape, serving as a complex artery between Washington and Oregon. Industrial activity is centered around the Crown Zellerbach Mill and the riverfront settlements of Bradwood, Wauna, and Westport. The map details the intricate slough and island system of the river, notably Puget Island with its network of farms and the Puget Island Grange. On the Oregon side, the Spokane Portland & Seattle Ry follows the southern bank, connecting smaller river towns like Clifton and Marshland, where the Marshland School once served the local community. Further south, the terrain rises into the Coast Range, marked by summits like Nicolai Mt and Clatskanie Mt. This survey illustrates the era's reliance on river-and-rail transport, showing how topography and water management, including the 17 Lower Cathlamet Dike, shaped the regional economy.
