| Title | Power shovel loading boulders onto flatbed train cars for Columbia River jetty, 1938 |
| Photographer | Staff Photographer Seattle Post-Intelligencer |
| Date | 1938 |
| Caption | These boulders are most likely for the building of Jetty "A", one of three jetties at the mouth of the Columbia River. The jetties maintain the depth and orientation of the navigation channel, creating a safe passageway for commercial and recreational vessels of all sizes. The jetties are composed of boulders stacked on top of each other and extending out into the ocean. The 6.9-mile South Jetty was constructed between 1885 and 1913. The 2.5-mile North Jetty was built in 1914 -1917, and the one-mile Jetty "A" was constructed in 1938-1939. |
