Ashgill Force
Geology
Ashgill Force falls where the South Tyne River breaks through the Scar Limestone. The limestone rests on softer shales that are more easily eroded and creates the undercut behind the waterfall (the undercut is similar to that at Gilbert’s Cave).
Etymology
Force is an evolution of the Old Norse foss for waterfall.
