Scope and Content Note
The Historic Oregon Nautical Charts consist of superseded navigational maps for the Pacific Coast from California to Washington, navigable rivers and bays on the Oregon Coast, and the Columbia and Willamette Rivers. The collection includes charts for Coos, Tillamook, and Yaquina Bays and the Coquille, Nehalem, Siuslaw, Umpqua, and Yaquina Rivers. The charts vary in scale from 1:10,000 to 1:1,000,000, with the maps of the Oregon coastal rivers and bays and the Columbia and Willamette Rivers providing the most detail.
In addition to depth soundings of the open ocean, the charts depict lights, buoys, and radio beacons along the coast; topography of lands near the coast or waterways; and jetties, rock formations, and reefs. The charts include some roads and other features along the coastline.
