Hiawatha Crater

Second suspected Greenland crater announced by NASA

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 second […]

Hiawatha Crater central peak

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 portion […]

Another crater?

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. I […]

Hiawatha?

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 […]

Tusk on Hiawatha

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 Impact: […]
