About this map

The Humptulips River meanders through a landscape defined by logging history and coastal wetlands in this mid-century survey of Grays Harbor County. Small riverside settlements like Copalis Crossing and Newton are connected by an Old Railroad Grade, tracing the industrial corridors that once moved timber toward the coast. Near the southern edge, the terrain transitions into the expansive Tidal Flat of North Bay, where numerous piling and piles mark old maritime infrastructure and water-bound commerce.

Agricultural activity is evident in the specialized Cranberry Bog and Cranberry Bogs complexes near Kurtz. These features, alongside landmarks like Langley Hill and Saddle Hill, illustrate a rural economy transitioning from early rail-based resource extraction to the more established drainage and land-use patterns of the mid-20th century. Named sloughs such as Campbell Slough and Jessie Slough further highlight the intricate hydrologic network feeding into the bay.
