Clatsop Spit dominates the northern edge of this coastal survey, marking the strategic entrance to the Columbia River. The map focus is largely maritime, documenting the vast expanse of the Pacific Ocean and the shifting sands of Social Security Beach. Navigational features are prominent, including the Entrance Range and the Lower Desdemona Shoal, which highlight the importance of maritime safety in these waters. On land, Jetty Rd provides the primary access along the narrow finger of the spit. This modern cartographic study uses township and range divisions to delineate the offshore and coastal boundaries, emphasizing the intersection of public land surveys with the dynamic Oregon shoreline.
