Description: Glen Tilt, from hillside east of Marble Lodge, looking north, Perthshire. Typical V-shaped valley along shatter belt. The valley has moraines on the middle slopes, low alluvial terraces and a river that is now being incised. It was originally V-shaped, but the talus and drift on the lower slopes make it appear more U-shaped. The valley follows the line of the Loch Tay Fault, one of a series of brittle north-east - south-west trending faults formed after the end of the Caledonian Orogeny. It is thought that this fault could have formed on the limb of late ductile folds during the final stages of this Orogeny, it is in close proximity to such a fold called the Boundary Slide. The valley never contained an active scouring glacier, hence the lack of a glacial U-shaped valley. The ice sheets at the time travelled right over the valley at an angle, the valley probably being filled with fairly static ice.
