Columbia River traffic and the expanding footprint of the Portland International Airport dominate the northern landscape of this mid-century survey. The terrain transitions from the river's Lemon Island and Government Island toward the residential grids of Northeast Portland, where geologic landmarks like Mount Tabor and Rocky Butte break the urban pattern. The map documents a period of significant infrastructure development, featuring the Banfield Expressway and the Portland Air Force Base alongside older established neighborhoods such as Laurelhurst and Hollywood. Local institutions are densely recorded, including the Morningside Hospital, the Parkrose Cem, and numerous parochial schools like St Joseph Sch. The southern half of the map illustrates the growing suburban density around Montavilla and Powellhurst, showing how the Union Pacific and Spokane Portland and Seattle RY shaped the industrial and residential development of the era.
