Mussels along the top and right, barnacles on the left, a sea star in the upper right middle, and hooman beans top and bottom. Geology not so much (basalt), but I really like this photo. Dana told me later this was the first time she'd seen a starfish in it's native habitat (we saw a LOT of them). I was a little surprised at the time, but I've realized since she just hasn't spent that much time at rocky coastlines. Most of her coastal visits have been unconsolidated sediments.
