2011 Map of Clatsop Spit

About this map

Clatsop Spit and the mouth of the Columbia River dominate this coastal survey, where the river's massive discharge meets the Pacific Ocean. This specific geographic point has served as a critical navigational waypoint for centuries. The map details the shifting maritime environment, including the Lower Desdemona Shoal and the Entrance Range, which guide vessels through one of the most challenging river bars in the world. On the landward side, Jetty Rd provides the only recorded access point into this dynamic coastal landscape, illustrating the narrow intersection of man-made infrastructure and the powerful natural forces of the Oregon coastline.
