Join writer and permaculturalist Edward Tyler as he walks the length of one of Britain’s most remarkable geological features: the Highland Boundary Fault. Spanning five episodes, Earth Lines uncovers the science, stories, landscapes, and people living along this ancient tectonic divide between Scotland’s Highlands and Lowlands. From seaside rocks to seismic recorders, distilleries to eco-museums, this is a journey into Deep Time, the living land, and the subtle lines written into our landscapes that shape the world around us.

Edward Tyler continues his journey along the Highland Boundary Fault, heading north-east to the popular village of Balmaha, on the eastern shores of Loch Lomond - a place where geology and landscape collide in plain sight.
On a shoreline walk in search of Serpentinite, the distinctive rock we first encountered back in Innellan, Ed traces the path of the Fault once more. Climbing to a viewpoint above the loch, he takes in a breathtaking panorama that makes the contrast between Highlands and Lowlands unmistakable - a geological dividing line written across the landscape.
Along the way, we learn how striking local features like Conic Hill and the string of islands across Loch Lomond aren’t random: they were formed by the same tectonic forces that shaped the Highland Boundary Fault, and now conveniently map out its invisible route.
