The geological origin of the Carolina Bays has been the subject of contentious debates since the 1930s when their regular shapes and orientations were discovered by aerial photographic surveys. The use of LiDAR has improved the study of the CBs by highlighting their features without interference from vegetation. Well-preserved CBs have a mathematically elliptical geometry that can be verifed by fitting them with ellipses using the least squares method.
