Major Cities Ice Depth During the Ice Age

Internet cartoon and geography fan XKCD made a diagram showing how thick the ice sheet was over the spot of the city 21,000 years ago.

The depths are

  • Boston 4,100 feet (1250 meters)
  • Chicago 2,950 feet (900 meters)
  • Montreal 10,170 feet (1.9 miles! or 3,100 meters)
  • Toronto: 6,890 feet (2,100 meters)

My home region was once under over a mile of ice.  To think this and the radical changes between then and now are 100 percent natural.  Nature is violent and climate change can be world altering.
