The Hopi have legends of the Arizona crater, something to the effect of god coming down to earth there. They either saw it in the past, or they were pretty savvy at noodling it out as such when all the Europeans were concluding it was a “cryptovolcanic structure”...
Thanks Axenolith and NormsRevenge.
Barringer Crater, better known as Meteor Crater, could have formed in human times in North America. Clearly the terrain for a long way around is worse for wear due to the impact itself, a fact that mitigates in favor of it being more recent than the largely speculative 50,000 year figure often seen. Estimates of its mass and velocity are quite wide.
