High Force is a waterfall on the River Tees, near Middleton-in-Teesdale, Teesdale, County Durham, England.[1] The waterfall is within the North Pennines Area of Outstanding Natural Beauty (AONB) and European Geopark.
Despite popular belief that it is the highest waterfall in England,[2] at 21.5 metres (71 ft), others have a longer fall: Cautley Spout, in Cumbria's Howgill Fells, is almost 180 metres (590 ft) high, and Hardraw Force, in North Yorkshire, has an unbroken drop of 30 metres (98 ft); whilst underground, on the flanks of Ingleborough, Fell Beck falls an unbroken 96 metres (315 ft) down the Jib Tunnel of Gaping Gill Hole.
The whole of the River Tees plunges over a precipice (cliff edge which is almost vertical) in two stages. In former times flooding created two separate falls, but after the completion of Cow Green Reservoir in the upper Teesdale this seldom happens now. In harsh winters the falls would freeze, creating cathedral-like ice formations.[citation needed]
High Force was formed where the River Tees crosses the Whin Sill – a hard layer of igneous rock (also seen at Hadrian's Wall and other locations). The waterfall itself consists of three different types of rock. The upper band is made up of whinstone, or dolerite, a hard igneous rock which the waterfall takes a lot of time to erode. The lower section is made up of Carboniferous Limestone, a softer rock which is more easily worn away by the waterfall. Between these two layers is a thinner layer of Carboniferous sandstone, which was baked hard when the Whin Sill was molten 295 million years ago. 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. The bedload (rocks that the river is carrying) is mainly composed of large boulders, which are rolled along the river bed. Upstream of the waterfall, the river is narrow; downstream, it widens and meanders.
Access to the northern bank is via a private footpath for which a fee is charged. The southern bank can be reached free-of-charge via a public footpath.
Notable visitors
J. M. W. Turner, the celebrated painter, arrived at High Force at 10:00 a.m. on 3 August 1816 to sketch the scene. He then travelled upstream to Cauldron Snout and eventually made his way to Dufton, across the fells, in inclement weather.[citation needed]
Arthur Young came with his wife on horseback from Durham in 1771:
- The whole river (no trifling one) divided by one rock into two vast torrents pours down a perpendicular precipice of near fourscore feet: The deluging force of the water throws up such a foam and misty rain, that the sun never shines without a large and brilliant rainbow appearing...
- After preaching at Cuthberton and in Teesdale, I went a little out of my way, to see one of the wonders of nature. The river Tees rushes down between two rocks, and falls sixty feet perpendicular into a basin of water sixty feet deep ...
