High Force

The Waterfall High Force after heavy rainfall

The High Force is a waterfall in the course of the River Tees in County Durham near Middleton -in- Teesdale in England. The waterfall is located in the North Pennines Area of ​​Outstanding Natural Beauty.

The teas falls on Waterfall High Force 21 m vertically in depth, which is about the height of fall of the Aira Force. The waterfall is indeed still often referred to as the highest in England, but these are the above-ground waterfall Cautley Spout waterfall or untirdische Gaping Gill.

The waterfall comes from the fact that the teas, soft ' rock strata has washed under which a layer of' hard ' ( here called Whin Sill ) dolerite is situated on the river now flows. Under the dolerite, however, are first again a 'soft' layer of sandstone and then also 'soft' layer of limestone. This stratification results in the river as he slowly removes the 'hard' dolerite, he washes the other rock layers faster and so a surplus arises, while the waterfall ever retires. By leaching now a 700 m long canyon is formed.

Since the tea is now regulated by the Cow Green Reservoir, the river now flows only in rare cases, two separate entities, as JMW 1816 Turner painted in a watercolor.
