Hiawatha Crater

Crater research team reveals tentative evidence at 2019 AGU
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[..
Top Science story in 2018 receives zero attention or follow-up in 2019
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[..
Hat tip from Steve Garcia posted December 31st on the Tusk
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[..
Hiawatha Discovery Team member Anders Bjork tweets 3D crater model
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[..
Second feature found inland of Hiawatha may be hinted 2nd Greenland 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.[..
A recurring thread as things develop in the short term
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[..
