Went in many years ago when the entrance was covered with rocks, waist deep water for about 20yds to a fall where the arching meets bedrock. Goes in a bit further now through very 'blocky' sandstone to a complete fall - possibly an infilled shaft as there are bits of timber in it. Rather muddy, especialy if you should, for 'some' reason need to lay on your back!!!
The level is shown on the plan on page 11 of Martin Critchley's Nenthead Mines book (1998 edition only). Intersects Caplecleugh North vein & Carrs Vein.
