@Graham__Hancock Don't waste your time debating that snickering fool. Reread this paper on the Hiawatha glacier. Pay special attention to the ice morphology within 100 km of the crater. All the ice is from the Holocene. I believe this is our smoking hole. https://t.co/xmCxJWHbFE

@randallwcarlson https://t.co/xmCxJWHbFE @randallwcarlson will you please reread Radiostratigraphy of Hiawatha Glacier section. I read it as saying there is no pre younger dryas ice within 100km of the crater.

@johnhawks I realize the current consensus is that Hiawatha impact crater is 57 years old. But after re-reading https://t.co/xmCxJWHbFE “Radiostratigraphy of Hiawatha Glacier” I remain unconvinced.
