Geologists are attempting to confirm or debunk the idea that a large part of Hudson Bay is a huge impact crater. Research is being done on minerals in the area to determine if this formation is a crater or not
I just wonder if they are taking into consideration that this impact may have taken place during an ice age? when there could have been up to 3 miles of ice above the earth.
This could cause many unforeseen variables for the geology of a impact of this magnitude
