Younger Dryas / Loch Lomond Stadial

The Younger Dryas / Loch Lomond Stadial was an abrupt period of renewed cooling between 12,900 and 11,700 years ago and has long been associated with the regrowth of glaciers in much of upland Britain.

Evolution of temperatures in the postglacial period, after the Last Glacial Maximum (LGM), showing very low temperatures for the most part of the Younger Dryas, rapidly rising afterwards to reach the level of the warm Holocene, based on Greenland ice cores. From Platt et al. 2017.

The Younger Dryas period was characterised by an abrupt return to severe cold conditions following ice sheet retreat when glaciers regrew, forming most significantly a large ice field running the length of the Western Highlands in Scotland. This ice field was the largest of numerous satellite ice fields, ice caps, valley glaciers and cirque/niche glaciers on several of the western isles and at other upland sites around Britain and Ireland.
