Geological evidence found in Ohio and Indiana in recent weeks is strengthening the case to attribute what happened 12,900 years ago in North America -- when the end of the last Ice Age unexpectedly turned into a phase of extinction for animals and humans – to a cataclysmic comet or asteroid explosion over top of Canada.
These stratum titles are mine, not Haynes's, by the way, so take them with a grain of salt, and read his article for detailed information. In order from most recent to oldest:
* Altithermal stratum. 9,000-10,000 RCYBP. Drought conditions prevailed, during which Archaic mosaic hunter-gatherer lifestyles predominate.
* Post-Clovis stratum. (black mat layer) 10,000-10,900 RCYBP. Wet conditions are in evidence at the sites of springs and lakes. No megafauna except for bison. Post-Clovis include Folsom, Plainview, Agate Basin hunter-gatherers.
* Clovis stratum. 10,850-11,200 RCYBP. Drought conditions prevalent. Clovis sites found with now-extinct mammoth, mastodon, horses, camels, and other megafauna at springs and lake margins.
* Pre-Clovis stratum. 11,200-13,000 RCYBP. By 13,000 years ago, water tables had fallen to their lowest levels since the Last Glacial Maximum. Pre-Clovis is rare, stable uplands, eroded valley sides.
I know the dates don't match up so much....yet,But, on the Atlantic side, and well inland.
These were not “sea people.” following a “kelp highway.”
And check your globe.
This is a long, long way from the Topper site.
And there are a whole bunch of nice places to live in between
Recent evidence for extraterrestrial impact, although not yet compelling, needs further testing because a remarkable major perturbation occurred at 10,900 B.P. that needs to be explained.
