USGS Topo · Published 2024About this map
The complex estuary and wetlands where the Columbia River meets the Oregon shoreline define this corner of Clatsop County. This environment is largely protected by the Lewis and Clark National Wildlife Refuge, which encompasses a labyrinth of islands and waterways such as Karlson Island, Long Island, and the winding Knappa Slough. On the mainland, the settlements of Knappa and Brownsmead represent the long-standing agricultural and maritime history of the region.
