The Columbia River forms the central artery of this 1952 study, where the state boundary between Washington and Oregon weaves through a complex network of islands and channels. Land use at this mid-century moment is defined by the industrial and transport infrastructure of the lower Columbia, including the Spokane Portland and Seattle railroad and numerous levees and dikes protecting low-lying tracts like Crims Island and Willow Grove.
