Just 20,000 years ago, Orkney was covered by a kilometre of ice, part of a huge mass that reached out beyond Scotland. Huge glaciers were sometimes in slow motion, and traces of their paths can still be seen today in the scrubbed sides of some of Orkney’s hills. Over the years, geologists such as the great Victorians Ben Peach and John Horne have found evidence of rocks carried by the glaciers, and in a new film by Selena Kuzman, Dr John Flett Brown and Dr Adrian Hall follow in their footsteps – and find some rocks that have travelled a long distance to reach Orkney. There will be time afterwards for questions, along with the launch of the new website Orkney Landscapes, a massive resource for schools and students and everyone who wants to find out more about Orkney’s rocks and landforms.
