The remains of Billingsgate Island of Wellfleet. Photographed at about low tide in 1991. Today all that remains of the island is a shoal exposed during very low tides. Blocks of stone behind the boulders of the original riprap sea wall are all that remain of Billingsgate lighthouse. The fate of Billingsgate Island may be a precursor for Cape Cod as the sea continues to erode the fragile land. Photograph by Dann S. Blackwood, U.S. Geological Survey.
