The discussions reflect high interest and engagement with examples like the revision of the crater's age from thousands to millions of years, and debates about its possible effects on climate and historical impact events. Tone varies from excited to analytical, emphasizing the importance of this revision in understanding Earth's geological history.
AgreementModerate agreement
Most discussions agree with the new dating of the impact structure to 58 million years, refuting earlier notions of a recent origin, indicating consensus or strong support.
InterestHigh interest
The discussions show high curiosity, especially about the implications of dating the crater to the Paleocene, seen in phrases like 'finally managed to date' and 'many riddles left,' which convey enthusiasm and engagement.
EngagementModerate engagement
Many comments reference specific research findings, methods, and implications, such as mentions of 'Argon Dating' and debates about links to the Younger Dryas, demonstrating deep engagement.
ImpactHigh impact
The discussions highlight the significance of the findings in revising impact history and their disconnect from previous theories about recent impacts influencing climate events, indicating high impact.

Hiawatha Crater has nothing to do with the Younger Dryas; recent analyses date it to over 50 million years earlier. All the evidence is compatible with solar outbursts at the beginning and end of the Younger Dryas. #YounerDryas #Impact #Sun #SolarOutburst

Our new article on Hiawatha impact structure's age is out! Much older (~58 Ma) than we initially thought and occurred during a broader upheaval in global climate. Low long-term erosion but maybe faster now? Overlying ice still weird. Many riddles left!

Hidden underneath over 3,000 feet of ice in Greenland, the Hiawatha Crater is one of the planet's largest impact craters, measuring 193 miles wide. This video reveals the age of the crater and discusses its discovery…
This third video in the series debunks pseudoarchaeological claims made by Graham Hancock in his Netflix documentary, examining misconceptions about history and archaeology.

@Third_Eye_Seeks The Hiawatha crater (suggested as candidate for YD impact structure) has been dated this year in the Late Paleocene (58 My).
