Ancient peaks and molten rock... These mountains have not always looked as they do today...400 million years ago, long before the dinosaurs, they were part of a huge mountain chain, higher than the Alps, that stretched from North America to Norway. Beneath those mountains molten rock solidified into granite. Tropical mountains... Millions of years of erosion wore down those craggy mountains and periods of warm, wet climate left rounded granite 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. Ice Age glaciers... Over the last 2 million years, global climate fluctuated regularly and Scotland had up to 18 distinct Ice Ages. In the Cairngorms 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. Cairngorms today... Today the Cairngorms are still changing, and frost, floods, landslides, peat formation, and human activity all continue to leave their marks on the landscape.
