High Cup Gill (or High Cup Nick or just High Cup), almost a geometrically perfect U-shaped chasm,[1] is a valley deeply incised into the Pennine scarp to the northeast of Appleby-in-Westmorland in Cumbria and within the North Pennines AONB in northern England.[1] It is considered to be glacial in origin, ice having over-ridden the area during successive ice ages. To its southeast is Murton Fell and Dufton Fell is to the north.
