Dentdale

Dentdale is a dale in the north-west of the Yorkshire Dales National Park in Cumbria, England, named for the village of Dent rather than for its river, and one of the few Yorkshire dales that drains westward, toward the Irish Sea, via the River Dee. The valley begins at Dent Head, where the Settle-Carlisle railway line crosses on a viaduct, and near Gawthrop the Dent Fault divides older Silurian and Ordovician rocks of the Howgill Fells to the north from Carboniferous limestone to the south; beneath the valley floor the mile-long Upper Dentdale Cave System is a Site of Special Scientific Interest for what it shows about how valley-floor caves form.
