This is Whale Rock, whose menacing, haunting presence taunts us at the entrance to Narragansett Bay, Rhode Island.
It is all that's left of a lighthouse destroyed by the Hurricane of 1938. In a sense, it has returned to its former self: a foreboding rock ledge, resembling a surfacing whale's back, that had been a threat to navigation until a lighthouse was established on this ledge in 1882. There had been many shipwrecks before the light was built.
Today, Whale Rock is what it was, except with the addition of a lump of concrete caisson jutting up from the stubborn rock ledge.
