About this map

The Chehalis River defines the drainage and development of this Washington landscape, flowing from the interior hills toward the complex tidal reaches of Grays Harbor. The industrial and maritime hubs of Aberdeen and Hoquiam sit at the river's mouth, where the North Channel, Middle Channel, and South Channel navigate through a network of islands including Rennie Island and Moon Island. Upriver, the valley supports a string of settlements like Montesano, Elma, and Oakville, many of which developed alongside the Burlington Northern Railroad corridor.

Further east, the terrain transitions into the Black Hills and the extensive Capitol Forest. Geologic curiosities are prominent near Rochester, notably the Mima Mounds within the Mima Mounds Natural Area Preserve. The southern portion of the map covers the Willapa hills and the northern edge of the Willapa Nat Wildlife Ref, showing a landscape heavily shaped by the timber industry and the protected wetlands of Johns River State Wildlife Area.
