High Force, Tees Valley

Despite popular belief that it is the highest waterfall in England at, 71 feet (22 m), others have a longer fall. However, High Force does have the largest volume of water falling over an unbroken drop when in full spate, thereby earning its Nordic name 'High Fosse'.
The whole of the River Tees plunges over a precipice (cliff edge which is almost vertical) in two stages. The wearing away of rock means that the waterfall is slowly moving upstream, leaving a narrow, deep gorge in front of it. The length of the gorge is currently about 700 metres.
