Allen West on the Black Mat at Pecos Conference

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 […]

Carolina 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 […]

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 […]

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 […]

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, […]
