Mile 340
South Jetty Columbia River, Fort Stevens SP
I set out to walk mile 340, the northernmost mile in the state of Oregon, because I was curious to document wrackline biodiversity where the Columbia River meets the Pacific Ocean at "Clatsop Spit". Opalescent squid is the most common taxa of squid distributed on the Oregon Coast.
