Description: Crag-and-tail feature at Duncryne, Gartocharn, Dumbartonshire. Looking east. This is a good example of a crag-and-tail feature formed when the glacier coming down Loch Lomond overrode a crag of a Lower Carboniferous volcanic neck. The boulder clay which was deposited in the 'tail' of this feature contains fragmental marine shells. The volcanic neck cuts Lower Old Red Sandstone sedimentary rocks. The high ground around Loch Lomond was a centre of ice accumulation during the main late Devensian glaciation (Dimlington Stadial) and also during the later Loch Lomond Stadial.
