Did a Meteor Set Off a Grand Canyon Flood?

Get this: scientists now think the asteroid that made Arizona’s Meteor Crater also triggered a massive landslide in the Grand Canyon—causing water to back up as high as a 20-story building! Driftwood and beaver tracks way above today’s river level finally make sense. The timing matches up almost perfectly: both the crater and the ancient flood date back about 56,000 years. Talk about a cosmic chain reaction! #Science #GrandCanyon #MeteorCrater
