The Small Isles comprise the Inner Hebridean islands of Rum, Eigg, Canna and Muck. The landscapes, rocks and fossils of these beautiful, remote islands tells of a drama involving erupting volcanoes, an ancient ecosystem that included dinosaurs and an ancient desert landscape. The geological history stretches back 3 billion years to the earliest events recorded on Earth. All four islands owe their origin to a group of three adjacent volcanoes that were active around 60 million years ago. Rum is the eroded remains of the magma chamber of one of these volcanoes. Eigg and Muck are part of the lava field that extends north from the Mull volcano and Canna lies towards the southern extent of the lavas that flowed from the Skye volcano. The final event that left a mark on these islands was the Ice Age that started around 2.4 million years ago. Its effect on the landscape was profound. The thick cover of erosive ice shaped the contours of the land into the hills and glens that we are familiar with today.

The geology of the Cairngorms was created on a timeline that stretches back hundreds of millions of years. Much of the land is underlain by granite that formed deep within the Earth's crust and 'surfaced' as the overlying layers of rock were stripped away by ice, wind and water. The bedrock is hard, and although the area has been heavily glaciated, still boasts 18 Munros, the highest of Scotland's peaks. The area attracts climbers, walkers and assorted adventurers who want to pit themselves against some of the most challenging conditions to be found anywhere in the UK. The plants and animals of the Cairngorms need to be hardy to survive the severe winter conditions. The higher reaches of the mountains are rich in montane vegetation such as lichen-rich heath and other habitats support many rare species.
