plunges over a precipice (an almost vertical cliff edge) in two stages. After heavy rainfall the river will also flow over the usually dry right-hand side channel, creating two falls. Very occasionally the river level will be high enough to flow over the central section of rock; the last recorded time this happened was in December 2015 after Storm Desmond. In harsh winters the falls have been known to freeze, creating cathedral-like ice formations. Access to the northern bank is via a private footpath on the Raby estate for which a fee is charged. The southern bank can be reached free of charge via the

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

Notable visitors

The painter J. M. W. Turner 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. Arthur Young came with his wife on horseback from Durham in 1771 and made the following comment:

After preaching at Cuthberton and in Teesdale, I went a little out of my way, to see one of the wonders of nature.
