The Columbia River serves as the central artery and state boundary in this 2017 survey, separating the urbanized north bank in Washington from the expanding suburbs of Oregon. Industrial and residential footprints in Camas and Washougal surround Lacamas Lake and Prune Hill, while the southern bank features the dense network of Gresham and Troutdale. The map illustrates a complex riparian environment of islands and sloughs, including Government Island and Lady Island, positioned between the growing metropolitan reaches of Vancouver and Portland. Significant land use is dedicated to transportation and recreation, evidenced by the Portland-Troutdale Airport and the northwestern edge of the Mount Hood National Forest. Local history is preserved in several small burial grounds like Knight Cem and Fern Prairie Cem, which sit amidst modern developments like Wood Village and Fairview.
