Geo 365: Dec. 26, Day 360: Serpentinite Shore?

I'm not absolutely positive, but the back wall of the cove here has the look of a serpentinite zone: loose and full of boulders. And if that stretch of Route 101 above and behind it is the one I think it is, it's the most troublesome reach along the Oregon coast. It's constantly slumping and sliding out, especially in wet weather, which, of course, is very common here. To be clear, I'm not certain this is either serpentinite, or the stretch of road I'm thinking of, but it looks right.
