A curious geological feature on the coast stretching from southern New Jersey to northern Florida is the presence of thousands of strange elliptical depressions like craters on the Moon, all aligned in the same direction. It is estimated that there were once as many as half a million Carolina Bays along the Atlantic coast, but only a few hundreds have survived. They occur in clusters with sizes ranging from a couple to several thousand acres. These bays are surprisingly rich in biodiversity with birds, migratory waterfowl and mammals. There is no theory to explain why they are elliptical or why they are so aligned.
