 The last glacier occupied this corrie or cirque approximately 10,000 to 11,000 years before present during the Younger Dryas stadial.This cold period, which is also known as the Loch Lomond stadial, was the last mini ice-age that brought glaciers and tundra conditions to the Scottish Highlands.The corrie is home to a number of bird species, including ring ouzel and snow bunting (in the spring and summer) and ptarmigan (also known as rock ptarmigan) (all year round).
