The Carolina Bays are discussed in considerable detail in Fireston’s fascinating book shown in Comment #37. The article also mentions signs of the comet having exploded over the Chicago area. Actually, Firestone’s book shows a view of Lake Michigan indicating that two objects may have crashed into the lake. After looking closely it seemed to me that there would have been 3 objects with the smaller one between to two larger ones. Look at a regular map and you can see the rounded edges. The alignment of many of the eliptical bays converge on that general area as well.
Happy New Year to all my fellow scientifically interested FReepers. It is a fascinating world out there.
Happy New Year to you too.
