Rock 366 : Day 245 : Cligga Head

Rock3661029

Day 245 : Last day in Cornwall and a walk to Cligga Head. Here the Variscan St Agnes Granite (on the left) intrudes into the late Devonian Gramscatho Group (upper to the right). The intrusion drives a geothermal system and there are extensive tin mine workings on the cliff top.
