The entrance is in an enlarged grike 50m down the dry valley from LANCASTER HOLE
A short drop leads immediately to a tight crawl followed by an awkward downward squeeze, immediately followed by a 6m climb. A section of narrow rift follows to a squeeze in the floor which opens out onto another 6m climb leading to the terminal rift. It is thought that this may lead to one of the avens in THE GRAVEYARD SERIES in LANCASTER HOLE. A smoke test prooved positive!
