A sea star and anemones in a tidepool at Cape Perpetua. How is this geology? You don't see tidepools unless the shore is rocky and resistant, like the basalt here. Anemones and sea stars do not live on sandy beaches. So the mere fact that we're seeing such creatures- even if I showed you nothing but the above photo, with basically no rock discernible- tells you a great deal about the geology around you.
