The main objective of this study was to test the YDB impact hypothesis by analyzing a wide range of data from the Pilauco site in southern Chile. The following conclusions show that our data and interpretations are consistent with the YDB impact hypothesis and we found no evidence that refutes the hypothesis. (1) At Pilauco, […]

The large variety of Hiawatha impactite grains containing terrestrial organic matter with a likely age between 2.5 Ma and 50 ka support the conclusion in [1] that the crater itself is not much eroded and very young, and the possibility of an age of less than 50 ka remains open.  

The bibliography of the subject alone refutes Vance Holliday’s absolute and categorical rejection of all evidence for the YDIH in a recent lecture. There are simply too many groups publishing too many papers for all of the evidence to be entirely rejected by anyone, even a persistent critic like Holliday. For gosh sake, the world’s […]

Only at the Cosmic Tusk can you expect to see a major global announcement by NASA scooped by six weeks. Thanks to our blog’s most dedicated contributor, Steve Garcia: You heard it here first. See other, non-prescient, contemporaneous coverage here: NBC:  Immense crater may have been found deep under Greenland’s ice sheet PhysOrg: NASA finds possible second […]

The Tusk doesn’t generally report on current impact phenomena, and focuses instead on past impacts. But it never hurts to show some cool videos on a blog. First is from terrified residents of Vianales, Cuba on February 1st, 2019, shocked by the delayed arrival of the concussion, and staring in wonder and disbelief at the […]

Long on the list of goals here at the Tusk is to host the world’s most concise, attractive, accessible and informative bibliography of our favorite subject. A baby step in that direction is submitted below for your perusal, download and propagation. With the help of Marc Young, here is a list of what we believe […]

11:05 No crater? 48:23 Jim Kennett in a wonderful moment During a fleeting period at the end of the last decade, a decade ago, the YDIH was a burgeoning mainstream topic. So popular in fact that the “Cadillac” of science TV, PBS NOVA, did an absolutely beautiful hour-long 2009 episode on the ice age comet discovery and […]

Some wag tweeted this funny cartoon today depicting the current state of affairs in Younger Dryas Boundary Research. The storyboard calls out The Bos and Vance Holliday for their willful ignorance with regard to the Younger Dryas Impact Hypothesis. The clever and extraordinarily well informed cartoonist points out the awkward position The Bos has created for […]

Jimmy at Bright Insight has posted a masterpiece of science and speculation concerning the YDIH. How do these guys do this? I would find it very, very difficult to prepare all this info and share it in such a coherent manner on camera. Some of his other videos are just tad too speculative, even for […]

As most crater heads know, a “central peak” within a bowl shaped depression is diagnostic of a large “complex crater” resulting from a highly energetic (to say the very least) cosmic collision. Though NASA made an effort to point out the subtle peak features of Hiawatha Crater beneath a mile of erosive ice, the portion […]

Longtime Tusk buddy and dedicated Catastrophist Steve Garcia went crater hunting and located IMHO a great candidate for the second crater hinted at by NASA scientist Dr. Joe MacGregor of the Hiawatha Discovery Team. He was thoughtful to send the Tusk the first image below of the suspect dimple beneath a mile of ice. I […]

Oh, lordy, bring me my salts. I do feel the vapours coming on. You could have knocked the Tusk over with a feather at the Apple Store yesterday when my phone linked to the The Bos in the Washington Post, presenting at 2018 AGU, and pimping to the world: The Taurids are a threat! The […]

Wow. The cascade of stupefying new discoveries continues. A paper published today in the Journal of Great Lakes Research provides evidence from gravity anomalies that Saginaw Bay in Michigan is a remnant feature of an impact into an ancient ice sheet. This and the recent discovery of Hiawatha Crater make for an interesting configuration. But […]

Seriously, it is really cool to see Science Magazine name Hiawatha Crater as 2018 breakthrough story runner up — and with due reference to the Younger Dryas Impact Hypothesis. The crater will be an intellectual gift that keeps on giving, and its better days are ahead. So I will go ahead and nominate the article […]

From my new friends, Brothers of the Serpent  Episode #078: George Howard We have a very special episode for all you snake sibs out there, we interviewed Mr. George Howard, who has been involved with the Comet Research Group from the very beginning in the work on the Younger Dryas Impact Hypothesis, which we have spoken […]

In the weeks following the Hiawatha Crater discovery, I took the opportunity to post a personal note concerning the Younger Dryas Impact Hypothesis on my Facebook page. Deeper in the thread as a result of some comments I took the opportunity to give my “2018 take” on the Carolina bays. Here is my comment, excerpted […]
