Scotland is divided into three main regions; the Highlands, the Midland Valley and the Southern Uplands. The cities of Edinburgh, Glasgow and Dundee together with numerous towns, most of the population and the majority of Scotland’s industry is located within the Midland Valley. This broad valley averages 50 miles across and runs WSW to ENE across the centre of the country. It is geologically distinct from the surrounding regions, being composed of Devonian Old Red Sandstone, peppered with ancient volcanoes, as against the older sedimentary rocks forming the Southern Uplands or the ancient metamorphic melange, comprising the Highlands to the north.
