Caption: "Pile Driver in the Breakers, Columbia River Jetty.," c. 1910. View of a large pile driver used in the construction of the jetty system at the mouth of the Columbia River. This is likely at the end of the so-called South Jetty, extending more than six miles into the ocean from Point Adams on the Oregon side of the river mouth. The jetty system at the mouth of the Columbia River was constructed between 1885 and 1917. Designed to funnel water from the Columbia River in a more concentrated fashion into the Pacific Ocean, the jetty system helped create a deeper, more stable shipping channel.
Date: 1910
