1955 Map of Copalis Beach

About this map

Copalis Beach and the coastal settlements of Grays Harbor County define this mid-century survey of the Washington shore. The landscape is dominated by the shifting Sand Dunes that separate the Pacific Ocean from a series of inland waterways and lowlands, including the meandering Connor Creek and Cranberry Creek. The map documents a period of coastal life where small clusters of development like Ocean City, Sampson, and Oyhut are linked by a narrow corridor between the dunes and the marshy interior. To the north, the Copalis River flows into the sea, while the southern portion of the sheet reveals the complex hydrology of the North Bay with its expansive Tidal Flat and the Oyhut Channel. Local landmarks such as Lang Lake and a small Cem provide specific points of interest for those tracing the geographic history of this peninsula.
