The rugged, wild, mountainous landscape of Rum owes its creation to a geological history that stretches back nearly 3000 million years. For such a small island the range of scenery is remarkable - from the jagged peaks of Askival and Hallival in the east, to the rounded hills of Orval and Ard Nev in the west and the flatlands of Kinloch Glen. The spectacular panorama from Rum encompasses the sloping back bone of Eigg, the rich green pasture of diminutive Muck and the caved basalt coastline embracing Canna and the low lying Sanday. Held together by the sea, these islands combine a richness of landform, colour and texture with the ever changing light and dramatic weather. Find out how this mecca for geologists was formed over millions of years in this riveting tale and ocean, volcanoes and glaciers.
