Just to be clear, this is in Maine Portland, not Oregon. Back side of the fishing shops and small docks. These docks are loaded with crabbing boxes, sounds like a popular type of fishing around here, who knew, haha.
Marco Island was a total shell fest. I was really surprised to see so many of them. On the east coast around NC/SC beaches you are not going to see that many shells. Marco Island beaches were packed with them. Pretty cool stuff. I took a few pictures with different concentrations and different sizes. You will have to see them all over the next few weeks.
This is closer to the south point on the beach, even after two days of calm weather there were still tons of them. And they were constantly moving.
