What is "grey friar"

Grey Friar is a fell in the English Lake District, it is one of the Coniston Fells and is situated 13 kilometres west-south-west of Ambleside. It reaches a height of 770 metres (2,526 feet) and stands to the north west of the other Coniston Fells, a little off the beaten track and tends to be the least visited of the group. It is quite a large fell and forms the eastern wall of the Duddon Valley for several kilometres, in fact all drainage from Grey Friar goes to the Duddon Valley and not to Coniston Water.
