The swift waters of the River Erme- here racing through the first of two Grade 4 ‘dog-leg’ rapids deep in the Upper section of the Erme Gorge - in the Longtimber Woods (on the fringe of Dartmoor National Park in South Devon. The ‘dog-leg’ falls at this point are some of the more challenging whitewater rapids descents in the UK - in spate conditions reaching Grade 5 or 6! * 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.
