The Columbia River serves as the dominant geographic divide on this 1961 survey, separating Vancouver in Washington from the expanding urban districts of East Portland. Distinctive volcanic landforms like Mount Tabor and Rocky Butte punctuate the grid of the city, providing elevated relief above the densely settled neighborhoods of Parkrose, Montavilla, and Hollywood. The mid-century infrastructure is well-defined by the massive footprint of the Portland International Airport and Portland Air Force Base adjacent to the Columbia Slough.
