[Rockhounds] Yarrabubba impact structure, Australia, dated to 2224 - 2234 Ma (end of Snowball Earth)

[J Bryan Kramer]

That had me confused until I figured out there were multiple snowball earth
episodes. The article I first read had a link pointing to the 600-700 MYA
snowball earth and it didn't make sense that this asteroid that hit more
that 6 GYA had anything to do with it

one, an unpitied sacrifice in a contemptible struggle.”
