2020 Map of Chinook

About this map

Ilwaco and the neighboring settlement of Chinook anchor this coastal landscape where the mouth of the Columbia River meets the Pacific. The area is defined by a complex network of waterways, including the Ilwaco Channel and the Wallacut River, which snake through tidal flats and marshes. Significant topographical features like Bear River Ridge and Scarboro Hill overlook the low-lying estuaries. The map documents the extensive protected lands of the Willapa National Wildlife Refuge to the north and the Lewis and Clark National Historical Park near Chinook Point. This coastal position has long necessitated strategic infrastructure, evidenced by the Fort Columbia Tunnel and a grid of local routes such as Chinook Valley Rd and the historic Military Road, which connect the small communities of Stringtown and the surrounding shoreline.
