1949 Map of Knappton

USGS Topo · Published 1976

About this map

The Columbia River shoreline and the timbered heights of Naselle Ridge define this coastal landscape as it was documented in 1949 and updated in 1973. Along the riverfront, the map captures the transition from water to land at Knappton, once a bustling cannery and mill site, and the small settlement of Frankfort near Portuguese Point. A significant Quarantine Sta sits on the shore between Cliff Point and Knappton, marking the historical importance of maritime health inspections for ships entering the river.
