View of Ballochmyle Quarry, Mauchline, Ayrshire

Although not from Arran, this historic image shows the huge scale of the dunes.

Ballochmyle Quarry, Mauchline. Ayrshire. Permian red desert sandstones showing large-scale aeolian (wind-blown) dune-bedding.

The view shows five quarrymen standing in front of the working face. The dune-bedding is composed of three large wedges, the bounding surfaces represent a time when the underlying dune was eroded prior to the deposition of the next dune.

New Red Sandstone of Permian age. The dune-bedding is often seen in the polished faces of the stone in buildings, monuments and bridges throughout Ayrshire and Glasgow.
