The valley is an example of glacial erosion: a U-shaped valley carved by an immense glacier as it passed through. The rocks are granite, formed about 100 million years ago. On the left is the 3,000ft wall of El Capitan, famous for its rock climbs and Half Dome is at the centre of the distant skyline

Selected structural features in southern England, the English Channel and northwest France. The distribution of the correlative Tilleul and Ogbourne Hardgrounds is shown; these are absent to the north-east of the Wight–Bray Fault and associated with Variscan basement thrusts across central southern England. The section at Winterbourne Kingston, on the Litton Cheyney Fault, shows a conglomerate of older Cretaceous debris derived from the overthrust hanging wall, deposited on a surface correlative with the Ogbourne Hardground (Gale, 2019a). The Ogbourne Hardground is absent in the marginal successions in Devon. 'Strahan's Hardground' at Lewes, East Sussex, is correlative with the Ogbourne Hardground.

The Cuillin Mountains on the Isle of Skye have some of the best glacial landforms in Britain. This remarkable example is a roche moutonnée, in the bowels of the Cuillin magma chamber. This gabbro has been rounded and deeply scoured by rock fragments trapped in the ice of a passing glacier.

The prehistoric shark found in a suburban town in Scotland The fossil was so complete experts could see remains of the last meal it ate, 330 million years after it died.

Fascinating story. The fossil is on display at the Hunterian Museum and Art Gallery in Glasgow.
