Long Crags - Northumberland
Long Crags is a prominent isolated rock outcrop situated to the east and south of Hedgehope Hill and Cheviot. They were formed by metamorphic changes to the volcanic lavas caused by the eruption of a mass of molten rock from the Cheviot and Hedgehope volcanoes some 400 million years ago. This eventually cooled to form the granite which comprises the central part of the Cheviot massive. This part is today typically covered by heather within a surrounding area of andesite larvas.
