The Age of Minerals
// Permian & Triassic
It’s hard to get a good feel for the sheer grandeur of the granite outcrops of southwest England simply by looking at a moorland tor. This view of the granite of Treen Cliff on Cribba Head near Porthcurno in the far west of Cornwall, however, shows the structure of joints really clearly. The picture was taken from the Logan Rock - a large, formerly rocking, stone eroded into a precarious, teetering balance until it was apparently toppled by a naval officer in the 19th century (if memory serves me).
