1 Introduction
Some of Britain’s most dramatic scenery is to be found in the Scottish Highlands. The sight of mighty Ben Nevis, the desolate plateau of the Cairngorms, or the imposing landscapes of Glen Coe can unleash the call of the wild in all of us. Although these landforms were largely carved by glacial activity that ended some 10,000 years ago, the rocks themselves tell of a much older history. The Highlands are merely eroded stumps of a much higher range of ancient mountains. This unit is an account o
