The Moine Thrust Belt is a linear geological feature in the Scottish Highlands which runs from Loch Eriboll on the north coast 190 kilometres (120 mi) south-west to the Sleat peninsula on the Isle of Skye. The thrust belt is a zone between an extensive landscape of rolling hills over a metamorphic rock base to the east and more rugged, terraced mountains with steep sides sculptured from weathered igneous, sedimentary and metamorphic rocks to the west. Mountains within the belt display complicated layers and the width of the zone varies up to 10 kilometres (6.2 mi). Often, summits of hard rock cap softer sedimentary rock layers visible on lower slopes. Ben More Assynt, in the centre of the belt, is a typical example that rises from a glen of limestone caves up through sandstone terraces to a quartzite summit cap.
