The Columbia River serves as the central artery and state boundary in this 2020 map, separating the Washington communities of Vancouver, Camas, and Washougal from the Oregon cities of Portland, Gresham, and Troutdale. The industrial and natural landscape is defined by the river’s complex channels and islands, including Government Island and Lady Island, alongside the legacy of the Fisher Quarry and the BNSF Railway. Residential growth is evident across Prune Hill and Grass Valley, while the southern reaches show the institutional presence of Mount Hood College. Local history is anchored by numerous burial grounds such as Fern Prairie Cem and Camas Cem, and the eastern edge transitions into the protected terrain of the Mount Hood National Forest. Notable water bodies like Lacamas Lake and Fairview Lake punctuate the urbanized grid, providing a clear view of how water and topography have shaped the development of the Portland metropolitan periphery.
