I remember reading about this they suspected it was a meteor impact in fact maybe the largest to ever hit the earth. At the time of the impact, they suspect it would have had a 2-mile ice sheet covering it making a huge crater. What we see remaining is the very bottom of this crater that could actually have been a thousand miles across. when the ice melted we were left with the damage caused to the to the land under the ice.

Could it have been formed during the Younger Dryas impact event? Seems like a big coincidence that it would be in the same area.
