The Braid and Blackford Hills dominate the landscape of south Edinburgh and are two large tapered masses of volcanic rock. In this virtual geology walk, we’ll travel across the hills, to discover two main lava flows of different composition with a thin layer of ash in between. We will explore the volcanic history of the area, the story of erosion and glaciation, and the views from the summits. The deep valley of the Hermitage of Braid between the hills also has an interesting origin, with ice and meltwater picking out the contrasts between different rock types.
Angus Miller will lead this virtual field trip for the Geological Society of Glasgow.
