I was looking at google earth in southeastern NC and noticed a posting about carolina bays. It said that these geological features were of extraterrestrial origins. This is incorrect, I am an environmental scientist and native of North Carolina that has conducted extensive research on these features. The leading theory of their formation is the result of wind and water erosion and depostion. These wetlands fill with water in the winter and early spring when the dominant wind direction is from the southwest. This generates waves and the waves created the ovoid shape with elogation occuring perpendicular to the wind direction. In the late summer and early fall as these waterbodies often dry out the winds change direction and come from the northwest. This results in a parabolic eolian sand ridge along the southeastern shore. There is no evidence of meteor impact or any other extraterrestrial origin. The statement that these are craters is a wide spread myth that no credible geologist would acknowledge. In addition they range in ages from 15,000 to 100,000 years in age which suggest a geological process and not a cataclismitic event.
