Carolina Bays
Carolina Bays is a nickname given to the decline of a land that forms a circular crater like on the moon.
This strange geological phenomenon occurred around the 1930s when the Atlantic coast would be photographed from the plane for the first time.
Reporting from Amusingplanet, Some previous scientists believe the Carolina Bays were created because of the impact of meteroit that fell on the Atlantic coast.
While from modern research this crater is too shallow to be said as a former meteroit impact. And there is no evidence to show the existence of a meteorite component.
There used to be half a million Carolina Bays along the Atlantic coast, but only hundreds of them survived or were preserved.
Woods Bay and Bannett's Bay in South Carolina are examples of preserved craters, because most are eroded naturally.
Now the remaining craters are home to a variety of living things, some are filled with water, some are forested.
