Does LIDAR work underwater?
FWIU in Grand Traverse Bay, Lake Michigan, there's a 9,000 year old stonehenge-like structure 40 feet underwater; that's 4000 thousand years older than Stonehenge and about 6000 years older than the Osireoin and the Pyramids.

There's not even a name or a wikipedia page for the site? There are various presumed Clovis sites which are now underwater in TN, as well.

- westurner 1y agoThat's a better source than what I found; > The site in Grand Traverse Bay is best described as a long line of stones which is over a mile in length. > [...] may be a prehistoric drive line for herding caribou Also speculation that the Sage Wall in Montana is simply a geologic formation.
