On August 19, 2012, high tide brought a lot of marine algae up into the wrack. Most were species normally attached to rocky or substrate or cobble. This material was detached, which was kind of surprising because there had been no recent storms or damaging waves. Nevertheless, there it was.

Above is a nice big blade of Chondracanthus, otherwise known as Turkish towel. Tattered remains are frequently encountered on exposed beaches. The wrack line is full of interesting algae and other things like shells, birds and floats. If you want to see some other things I have encountered in the wrack, check out my Wrack Line pages.
