| Description: | Glen Quey, looking east, 6 km. north-east of Dollar, Tayside Region. Conspicuous ice-marginal gravel fan/delta, composed of material with a south-westerly derivation, built up by waters draining eastwards through Glen Quey. The fan is now deeply dissected by postglacial drainage. As the ice began to retreat at the end of the last major glaciation, the valley of the Forth Estuary, and tributaries like Glen Devon, were still full of stagnant masses of ice which blocked natural drainage routes. Waters flowing eastwards via the Dollar - Glen Quey gap built up terraces and a large gravel fan/delta into the flooded Glen Devon. When the impounded waters were eventually released, the gravel fan became dissected by normal terrestrial drainage. |
