* A period of mountain building towards the end of the Carboniferous (known as the Variscan Orogeny) resulted in the spectacular folding and faulting of the Carboniferous rocks. A general uplift of the area that is now Devon came to form mountains, possibly up to 3,000m high. Under a subtropical, arid climate, large amounts of sediment from the mountain chain were swept down by temporary rivers to the surrounding desert valleys and plains.
