Ice Age Times
The Cairngorm mountains have not always looked as they do today ... 400 million years ago, long before the dinosaurs, they were part of a huge mountain range, higher than the Alps, that stretched from North America to Norway.
Millions of years of erosion wore down those craggy peaks and periods of warm wet climate left rounded summits and shallow valleys. Today, that ancient rolling landscape can still be seen on the high Cairngorm plateau but elsewhere, the Ice Age glaciers changed things completely.
Over the last 2 million years, global climate fluctuated regularly and Scotland had up to 18 distinct Ice Ages. In the Cairngorms National Park you can see signs of ice action everywhere. Steep glens and corries, ice scoured rocks and vast heaps of sand, gravel and other rock debris are just a few of the features left behind by the glaciers.
