Geologists Dr John Flett Brown and Dr Adrian Hall set off to look at the sea-cliffs of Orkney’s west coast. The dynamic duo explore the Old Red Sandstone along the shore and discuss the effects of monster waves in Atlantic storms. “Few coasts on Earth,” they declare, “match the magnificence of these cliffs, caves and geos.”

This event is also part of the Scottish Geology Festival, hosted by the Scottish Geology Trust this autumn to encourage activity and events about Scotland’s geological heritage.
