Is there really a Cosmic Tusk?

Well, maybe. Maybe not. But I do own one of the largest intact Woolly Mammoth tusks found in recent years, and it has starred in a National Geographic episode as a potential relict of the bad times. There are indeed some unusual features to my tusk; odd marks, iron blotches, magnetic areas and such. It is currently under study by Jon Hagstrum when he is not working at USGS. In fact, Jon…

Carolina bays....in the Midwest?

Here’s an excellent mash-up of bay LiDAR images Rick Firestone used in a recent article he wrote for the Journal of Cosmology,  The Case for the Younger Dryas Extraterrestrial Impact Event:  Mammoth, Megafauna and the Clovis Extinction, 12,000 Years Ago. Why is it excellent?   Because perhaps it will inspire people to take this phenomena a little more seriously.  For instance, those who…

Clovis population decline at Younger Dryas?

One of the original 2007 Acapulco AGU posters: Recent evaluation by the author of the South Carolina Paleoindian point database indicates the substantial presence of a suspected Middle Paleoindian point historically known as Redstone (Cambron and Hulse, 1964; Mason, 1962; Perino, 1968; Williams and Stoltman, 1965). When compared with the known abundance of Clovis points in South Carolina, a…

New Paper: Sea Level jump at onset of Younger Dryas?

There was an interesting paper from Science last week concerning sea-level rise in and around the Younger Dryas.  It looks  as though there may have been a relatively small — but dramatically fast–  rise in Sea-Level just before the YD: Deglacial Meltwater Pulse 1B and Younger Dryas Sea Levels Revisited with Boreholes at Tahiti, from Edouard Bard, Bruno Hamelin, Doriane…

Firestone and Topping 2001

The excitement when this scientific paper was published in 2001 was old news to me, really. I had first heard from William Topping way back in 1998. He was interested in Carolina Bays. Terribly interested. So was another scientist he said, Dr. Richard Firestone. I hit the search on Alta Vista and lo and behold, Firestone is indeed a San Francisco nuclear scientist — for the government. That…
