In high spate, one of several risings at the head of Penyghent Gill. Pottering around Giants Graves. Phil Ryder peers into one of many entries to the little known caves at the head of Penyghent Gill. The black area to the lower right is the main stream in flood – very peaty. This entrance seems to be unrecorded so this may be a FIRST DESCENT! Needs further exploration when water levels subside.
