A lot of the interesting features on Scottish mountains (e.g. very obvious periglacial trimlines) date to this period.

Edit: It's interesting that the article talks about multiple impacts - including one in the Middle East, perhaps the origin of what became the accounts of the destruction of Sodom and Gomorrah. Complete speculation on my behalf, of course!
