When sea levels were 400 feet lower during the Ice Age, I wondered how much
more of Rockall would have been above water:

If you watch time-lapse animations of sea levels throughout the eons, you'll
notice that toward the end of the last Ice Age there are a couple of large
islands to the northwest of Ireland and to west of Scotland. Were they ever
inhabited like Doggerland?
