  1. Grand Canyon landslide-dam and paleolake triggered by the Meteor Crater impact at 56 ka: pubs.geoscienceworld.org/gsa/g -> An Asteroid #Impact May Have Led to Flooding near the #GrandCanyon: eos.org/articles/an-asteroid-i - there’s remarkable synchronicity between the timing of a paleolake in what is today Grand Canyon National Park and the formation of nearby #Barringer Meteorite Crater.

  2. #Barringer #Crater is nested in the Arizona desert with a depth of 570 feet (174 meters) and 4,100 feet (1.25 kilometers) across.

    The impact is estimated to have occurred between 49,000 and 50,000 years ago, and is believed to have been caused by an iron-nickel meteorite, about 130 feet (40 meters) wide.

  3. #NYT 📆 Jan. 26, 2023 The #asteroid about the size of a truck 🚚 (10m across) did not hit #Earth 🌎 but was one of the #closest #approaches ever by such an object, hurtling past Earth at just 2,200 miles above its surface. It was #unknown to #NASA, or anyone, until last Saturday nytimes.com/2023/01/26/science

    The object that excavated the #Barringer #crater was about 50 m across en.wikipedia.org/wiki/Meteor_C
