‘Mountain scenery is always inspirational; but understanding how mountain landscapes have evolved deepens our perspectives of time and space, and the transience of human existence.’

Mountains represent the essence of Scotland’s scenery. Postcards, calendars, shortbread tins and dishtowels seeking to capture ‘Scotland’ in a single image almost invariably depict a mountainous Highland landscape, sometimes with a loch or castle in the middle distance and a kilted bagpiper artfully (and sometimes digitally) inserted in the foreground. They are a fundamental part of Scottish identity, for though most Scots live in the towns and cities of the lowlands, the mountains are close by on the horizon, a line of purple or snow-covered peaks that reminds us of another Scotland where the interplay of sunshine and cloud over rocky crags, deep lochs, windswept plateaux and lonely moorlands creates a sense of wilderness and an opportunity to escape from our urban hinterland.
And escape we do. When the weather is favourable, thousands of hillwalkers visit the summits of Scotland’s mountains every week, many with the aim of completing the ascent of the 282 Munros (summits over 3000 feet or 914 m). Rock climbers are drawn to the crags and corries of Skye and Glen Coe, skiers to the snowy slopes of Glen Shee and the Cairngorms, and others come to the mountains for fell running, mountain biking and even hang gliding. Outnumbering all of these, however, are the visitors who come simply to marvel at the most wonderful scenery in the British Isles.
Nobody who has explored the mountains of Scotland can fail to have been impressed by their sheer diversity. The isolated sandstone peaks of the far northwest, the serrated gabbro ridges of Skye, the granite high plateaux of the Cairngorms, and the rolling uplands of southern Scotland represent a variety of mountain landscapes that rivals any on Earth. Such diversity
reflects not only Scotland’s tumultuous geological evolution, which has created a mosaic of contrasting rock types, but also the operation of a wide range of erosional processes that have sculpted the underlying rocks into the wonderful topographic variety of Scotland’s mountain landscapes. Some of these processes operated in deep time, many millions of years ago, others throughout the
Ice Age, and many, such as frost action, rockfall and river erosion, have continued to modify mountain landscapes since the disappearance of the last glaciers.
In this book we shall take a journey through time, beginning with the formation of the oldest rocks and ending with the manifold processes that are still operating on high ground. We shall visit past eras when Scotland lay near the Equator, when alpine-scale mountains towered over the landscape, when volcanoes spewed out copious lava flows, when ice covered the land, and when earthquakes triggered major landslides. Mountain scenery is always inspirational; but understanding how mountain landscapes have evolved deepens our perspectives of time and space, and the transience of human existence. Just 12,500 years ago, for example, Scotland looked like high-arctic Svalbard today: a great icefield occupied the western Highlands, a valley glacier was advancing to the southern end of Loch Lomond, permafrost underlay the ground beyond the glaciers and mean July temperatures were no higher than those in November at present. Understanding such events and their effects on the landscape can make a day in the Scottish mountains a thrilling excursion that spans millions of years.
