UCSB Press Release

From a University of California – Santa Barbara Press Release: “In the entire geologic record, there are only two known continent-wide layers with abundance peaks in nanodiamonds, impact spherules, and aciniform soot. These are in the 65-million-year-old Cretaceous-Paleogene boundary layer that coincided with major extinctions, including the dinosaurs and ammonites; and the Younger…

Tree falls in forest and one hand claps: Science press picks up Mexican Black Mat study

This just in from Popular Science, link here. Massive Extraterrestrial Rock Hit Earth 13 Millennia Ago, According to Nano-Evidence About 13,000 years ago, a chunk of a comet or asteroid hurtled into the atmosphere at a shallow angle, superheating the atmosphere around it as it careened toward the surface. The air grew hot enough to ignite plant material and melt rock below the object’s flight…

PNAS: New evidence from Central Mexico supporting the Younger Dryas extraterrestrial impact hypothesis

NOTE:  This post will be “stuck” to the top of the page for the time being. Related new material such as news articles and observations will be blogged subsequent to this post but will appear below. The old “Drudge Siren” is getting quite a 1st quarter work out. And from what I hear it is only the beginning. West, Kennett, Bunch and nearly a dozen new experts…

Alaska Big Wave at 12,900?

One of the many fun things about blogging is that ideas, speculation, and research will often come in “over the transom” from readers. I was recently contacted by Mr. Carl Blanchard with what appears to be long simmering evidence of an Alaskan mega-tsunami at our favorite time period, the Pleistocene-Holocene transition. It would not garner a post but he makes references that…

Seek and Ye Shall Find: ET material confirmed in Murray Springs Black Mat

At the end of the Pleistocene a Younger Dryas black mat was deposited on top of the Pleistocene sediments in many parts of North America. A study of the magnetic fraction (~10,900±50 B.P.) from the basal section of the black mat at Murray Springs, AZ revealed the presence of amorphous iron oxide framboids in a glassy iron-silica matrix. These framboids are very similar in appearance and…

Abstract

At the end of the Pleistocene a Younger Dryas “black mat” was deposited on top of the Pleistocene sediments in many parts of North America. A study of the magnetic fraction (~ 10,900 ± 50 B.P.) from the basal section of the black mat at Murray Springs, AZ revealed the presence of amorphous iron oxide framboids in a glassy iron-silica matrix. These framboids are very similar in appearance and…

Tar Hell: Carolina coast and the UK catastrophically inundated by tsunami circa 1000 AD

I have always been personally curious about the lack of documented evidence for a tsunami ever occuring on my home coast of North Carolina. Some of the largest undersea land slides on earth have been documented off our wonderful Outer Banks, and earthquakes are not completely unknown in the Carolinas. Both cause big waves. But more to the point for the Tusk, some very credible work has documented…
