It’s known to ships and seafarers the world over. But when did it form? And how did its coast evolve, through ice and waves and storms? Edinburgh geomorphologist Dr Adrian Hall finds out at first hand, with helpers including Katy Firth of Stromness Museum and Mara Gibb from UHI in Caithness and Sutherland. Follow them in Selena S. Kuzman’s new film as they explore the shores of Hoy, from Brims and the Green Heads to Rackwick and the Old Man, then to Caithness to see the Stacks of Duncansby, Gills Bay, Dunnet Head, Forss and Reay; and on to Stroma. They go on to launch the new Caithness Landscapes website, to accompany the Orkney Landscapes site. There’s time for questions afterwards, and in the tea break.

The production of the film has been made possible through the kind support of Thistle Wind Partners.

This event is also part of the Scottish Geology Festival which runs from 1 September to 6 October with a rich mix of indoor and outdoor events across Scotland.
