Cathlamet serves as the focal point for this riverside survey, situated where the Columbia River splits into a complex network of channels and sloughs. This era reveals a landscape defined by its waterways and islands, including Tenasillahe Island and the Hunting Islands, where levees and sloughs like Bernie Slough and Welcome Slough dictate the movement of goods and people. Along the Oregon shore, the Spokane Portland and Seattle railroad follows the riverbank, connecting industrial and residential outposts such as Bradwood and Clifton.
