Geomythology

An interesting web site to view is at http://tsun.sscn.ru/hinsg/data.htm which has four maps of the world. On them are marked confirmed impact structures, some 180 of them on the continental surfaces and just 24 known from beneath the oceans. The maps also mark out evidence of historical tsunami events.  On the same web site, the Holocene Impact Working Group, are a number of interesting pages including a Timeline of Activities.

The case of the younger dryas extraterrestrial impact event

An article in Journal of Cosmology volume 2, pages 256-285 Oct 27th 2009, 'The Case for the Younger Dryas Extraterrestrial Impact Event: Mammoth, Megafauna, and Clovis Extinctions 12,900 Years Ago' by Richard Firestone can now be downloaded in pdf format (17 pages of print) at http://journalofcosmology.com/Extinction105.html . Firestone, of Lawrence Berkeley National Laboratory in California, outlines his arguments in a pretty effective manner - with copious references.

More on the AGU Fall Meeting

George Howard's web site http://cosmictusk.com has a post on a talk by Tom Stafford, author of Redefining the Age of Clovis; Implications for the Peopling of America which was published in the journal Science in 2007. Stafford's talk at the AGU conference laid out details of a very narrow layer of evidence at the Younger Dryas boundary, at a site in Texas, a thin 1 to 2cm layer of material that was host to trillions of nano-diamonds and high levels of soot known as aciniform.

Catastrophic Scenarios (real or imagined)

Science Daily January 27th ... the Neanderthals are now said to have died out in Iberia 37,000 years ago, coinciding with dramatic changes in climate and environment. Accurate C14 dating was achieved via the Vienna Environmental Research Accelerator from a sample of cave sediment. This date is 5000 years younger than the demise of Neanderthals north of the Pyrenees but C14 techniques are notoriously difficult around the upper limits at 40,000 years ago. The new C14 methods developed in laboratories such as Vienna are thought to be much more reliable.

Younger Dryas Event Update (January 2009)

George Howard, on his web site/ blog http://cosmictusk.com is reporting on the Fall Meeting of the AGU which included a session on the Younger Dryas boundary event. In the first of what will be several reports George begins with two speakers, Wally Broecker on the sceptics side, and Allen West, on the pro.

Flood mystery solved

Researchers believe they have found evidence of the formation of the Mediterranean Sea, five million years ago. Their findings suggest a 200km channel from the Atlantic Ocean, and carved out through the Gibraltar Stait, could have filled the low-lying land in just two years, raising the water level by 10 metres per day.
