1951 Map of Clatsop Spit

USGS Topo · Published 1955

About this map

Fort Stevens Military Reservation anchors the coastal landscape where the Columbia River meets the Pacific Ocean. This coastal survey documents the strategic maritime and military infrastructure at the mouth of the river during the early 1950s. The geography is dominated by the shifting sands of Clatsop Spit, where a Lookout Tower and a South Jetty monitor the treacherous transition from river to sea. Navigational hazards and engineering efforts are visible throughout the waters, including a Submerged Breakwater, various Piling locations, and a Tidal Flat. The presence of a Bridge Unsafe label near the spit suggests the physical challenges of maintaining access in this dynamic environment of salt spray and moving dunes.
