Hiawatha Crater

Hiawatha Crater: still smokin'?

I’ve previously posted my frustration with the silence concerning the presumably on-going research to characterize and date this extraordinarily young impact crater in Greenland. I’ll put that rant aside, and repeat the establishment line here (unchanged since the discovery): The cosmic impact crater creating, climate changing, 5-mile deep, 19-mile wide, bowl of molten rock is…

Ancient tree and plant parts found in Greenland's youthful Hiawatha Crater

Hiawatha Crater

Fourteen months ago the Tusk could not have been happier. Science Magazine not only addressed the Younger Dryas Hypothesis for the first time in a decade, but did so in a lavish, well-written article. The article accompanied the announcement of what seemed could be the long sought ‘smoking gun’ of the YDIH: A massive crater dating to the start of the Younger Dryas. The astounding…

Second suspected Greenland crater announced by NASA

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 impact crater under…

Hiawatha Crater central peak

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 of their video revealing this crucial aspect of the…

Another crater?

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 dug up some others below that. Here is MacGregor’s hint in…

Greenland icebergs may have triggered Younger Dryas

This paper from five years ago seems consistent with the Hiawatha Impact Crater. Some 13,000 years ago, as the last Ice Age seemed to lose its cold grip on the Earth, the temperature suddenly plunged again. Up to now, scientists believed that the Younger Dryas cold reversal was caused by great amounts of Canadian meltwater flowing out into the North Atlantic and cooling it after an ice barrier…

Tusk on Hiawatha

What a week. The announcement of the Hiawatha Crater is hands down the most important development in the eight year history of the Tusk. Lest I remind you, when your blog’s tagline is “Exploring abrupt climate change induced by comets and asteroids during human history”, and Science publishes a feature article titled: Ice Age Impact: A large asteroid struck Greenland in the time…
