2011 Map of Cathlamet

About this map

Tenasillahe Island and the complex web of the Columbia River define this stretch of the Pacific Northwest border. The map documents the intricate hydrology of the estuary, where major landmasses like Puget Island are threaded by Birnie Slough, Brown Slough, and Duncan Slough. The settlement of Cathlamet serves as a focal point on the Washington side, connected to the island by the Puget Island Bridge. On the Oregon bank, the small communities of Westport, Wauna, and the vanished site of Bradwood represent the industrial and maritime history of the river, with the Westport Post Office and local landmarks like Hunts Mill Point anchoring the riverfront. The terrain transitions from the low-lying Lower Elochoman Valley to the elevated relief of Oklahoma Hill, illustrating how the geography dictated the placement of early infrastructure like the Puget Island Ferry Landing.
