This is a 1915 nautical chart titled Columbia River: Entrance to Harrington Point, published by the United States Coast and Geodetic Survey.
The map depicts the entrance to the Columbia River at the border of Oregon and Washington, including the coastline from Cape Disappointment and Point Adams to Astoria and Harrington Point. It details bathymetric soundings in feet, navigation channels such as the Main Ship Channel and South Channel, shoals like the Tansy Point Shoal, and infrastructure including the south jetty and the port town of Astoria.
The chart includes aids to navigation, such as buoys and lights (with seasonal lighting schedules), tide tables, compass roses, and guidance for “Rules of the Road” for inland navigation. It also shows roads, railways, and selected structures on land. This edition, dated March 1915, reflects early 20th-century hydrographic surveying techniques and remains a significant historical document for understanding navigation and settlement along this key Pacific Northwest waterway.
