Morning glory…This is one of my all time favourite Bamburgh compositions.
These rocks are part of the “Whin Sill”, a huge sheet of molten magma that forced its way between layers of older sedimentary rock around 295 million years ago. The magma never reached the surface; instead it cooled slowly underground and solidified into an extremely hard rock called quartz dolerite (often called “whinstone” locally).
