[7] Whilst fishing on the Dee at Dentdale in the 1840s, William Armstrong saw a waterwheel in action, supplying power to a marble quarry.
It struck Armstrong that much of the available power was being wasted and it inspired him to design a successful hydraulic engine which began the accumulation of his wealth and industrial empire.
[13] There are over 200 listed buildings and structures in Dentdale which include the railway viaducts, bridges, barns, farmhouse, mileposts and even telephone boxes.
Western Dales Bus operate a year round Saturday and summer Sunday service between Dent station and Sedbergh with stops en route.
[22] The Dent Fault cuts across the valley close to the village of Gawthrop, marking a geological boundary between the Carboniferous Limestone of Deepdale and the Craven Dales to the south and the older Silurian and Ordovician rocks of the Howgill Fells to the north.
[23] The Upper Dentdale Cave System, which is 2 miles (3.2 km) east of Dent, was recognized as a site of Special Scientific Interest (SSSI) in 1998.
