Amazing LiDar Images of the Bays:

The survey is enabled with LiDAR imagery. This relatively new technology allows the production of Digital Elevation Maps (DEMs) which have spectacular fidelity, often being able to discriminate elevation changes of only a few tens of centimeters, with spatial resolution measured in 2 to 3 square meter grids. For a great overview of the technology, you might start with this discussion about the Coastal Georgia Elevation Project .
It is well known that “Carolina bays” exist far north of the Carolinas. In Virginia, Maryland and New Jersey, they become more rounded, confounding the search for an obvious orientation. We see the bays forming a “bell” planform, with the narrow top pointing back along the orientation, and the wide base at the far end of the structure.
