Stranded Marine Mammals
Total stranded mammals: 1. See photo. We saw a person from Portland State Univ. dissecting a stranded sea lion. According to this person, the seal ion was pregnant and eight shot-gun pellets were removed from the dead body. Her thinking was that the sea lion had been sunbathing on the close-by jetty rocks and was shot.
Natural Changes
Visible retreat of solid bluff. There was direct evidence of continuing dune retreat as the dune system migrated eastward uncovering previously deposited fine-grained, compacted, dark sand - see photo.

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.
