1951 Map of Clatsop Spit

USGS Topo · Published 1984

About this map

Fort Stevens State Park anchors the shoreline where the Columbia River meets the Pacific Ocean. This bathymetric study documents the shifting sands and strategic maritime infrastructure of Clatsop Spit during the mid-20th century, with late-century revisions tracking changes to the river's entrance. The inclusion of a Submerged Breakwater and a massive Jetty highlights the ongoing engineering efforts to maintain safe passage for vessels entering the river. Near the spit's edge, noted Ruins and the enclosed Jetty Lagoon hint at the area's long military and maritime history. Detailed depth contours and designated Dump Sites reflect the industrial and navigational demands of the Columbia Bar, a waterway defined by its complex currents and sediment movement.
