Younger Dryas

The Younger Dryas stadial, named after the alpine / tundra wildflower Dryas octopetala, and also referred to as the Big Freeze , was a brief (approximately 1300 +/- 70year http://www.agu.org/revgeophys/mayews01/node6.html#SECTION00060000000000000000) cold climate period following the Bölling/Allerød interstadial at the end of the Pleistocene, and preceding the Preboreal of the early Holocene. In Ireland, the period has been known as the Nahanagan Stadial, while in the UK it has been called the Loch Lomond Stadial.

An Older Dryas stadial had preceded the Allerod, approximately 1000 years before the Younger Dryas; it lasted 300 years http://www.geo.arizona.edu/palynology/geos462/02holocene.html.
