This picture was taken by Jim Riding in 1998 from the summit of Croagh Patrick, looking northwards over Bertra Strand towards the islands of the inner part of Clew Bay. It is said that there are 365 islands here, all of which are "drumlins" which are small hills, facing east to west, which were laid down by glaciers in the last great Ice Age. At the west end of almost all of them the Atlantic has formed vertical cliffs of boulder clay.
