Aysgarth Falls are a series of waterfalls over a one mile stretch of the River Ure in the Yorkshire Dales. In additional to the waterfalls the banks of the river in this area contain many potholes (round / oval shaped holes in the bedrock of the river bed).
The video below shows examples of potholes close to Aysgarth Falls.

High Force is a spectacular waterfall on the River Tees in the County on Durham. High Force was formed where the River Tees crosses the Whin Sill – a hard layer of rock. The waterfall itself consists of two different types of rock. The upper band is made up of whinstone, a hard rock which the waterfall takes a lot of time to erode. Underlying the whin sill is a layer of of Carboniferous Limestone, a softer rock which is easily worn away by the waterfall. This creates a plunge pool beneath the waterfall. As the limestone is eroded the whin sill is left over hanging the waterfall. Eventually the overhang collapses.
If you are in the area it is also worth visiting Low Force.

Throughout its course within Swaledale the River Swale is very fast flowing, and prone to rise rapidly in times of flood. The river rises on the slopes of High Seat and Nine Standards Rigg and becomes known as the Swale at the point where the becks of Birkdale and Great Sleddale meet. The river descends rapidly towards Keld, with a waterfall at Wain Wath Force, before descending into a narrow gorge below Keld and over Catrake Force, followed by Kisdon Force. From here the river descends a further 200m along the next 20 miles to Richmond Bridge. The steep sided tributary valleys also contain a number of spectacular waterfalls.
