Selena S. Kuzman’s new film is her most ambitious yet, a groundbreaking visualisation of the enormity of geological time. Geologist Adrian Hall is joined once again by presenters Mara Gibb from Caithness and Katy Firth from Orkney on a grand scenic journey. The vista rises out over Scaraben, the ancient island mountain, and soars over the wart-like tors on Smean, touching some of the oldest rock surfaces in the British Isles. They are blown away by the young, dynamic sand hills at Dunnet Bay.

Crossing to Stromness, they’re off to Brinkie’s Brae, a granite stump of the once mighty Caledonian mountain chain. And over on Shapinsay, where they find pristine Devonian lava flows and boulder clay streamlined by the passage of the last ice sheet.

Their travels include Timespan by the river in Helmsdale and round off outside the red sandstone of St Magnus Cathedral with a welcome from Orkney storyteller Tom Muir.

All along the way, they ask: How quickly do our hills form? And how long do they last?

Join the journey to imagine what can happen on the Earth’s surface over a millennium, an Ice Age, or even a hundred million years.

The production of this film has been made possible by funding from EventScotland.
