WARNING
The furthest upstream entrance in the true left bank of EASE GILL BECK, in a long open depression. A short low crawl and a climb down enter a chamber where daylight enters from a fenced shaft 6m above situated on the bank of the gill (see photo above). The way on drops to a wide crawl and a second chamber. Passage straight ahead ends in a mud choke after 37m. This may connect to MAGPIE CHAMBER in POOL SINK if dug.To the right leads to a clean washed passage which originates in an inlet chamber with a roof connection to the daylight chamber at the entrance.The way forward is a flat out crawl under the left wall to a short drop into a dark aven. Tortuous passages enlarge to a shingle crawl which chokes where a small downhill tube, BAR STEWARDS PASSAGE, meets a high inlet dropping to a fine 15m pitch. Belay to a blade of rock directly over the pitch. before BAR STEWARDS PASSAGE a tight shingle floored crawl goes off to the right. This leads to a series of exposed climbs dropping 12m to the main inlet passage at the upstream end of FUSION CHAMBER.
Below is the Massive FUSION CHAMBER with a
complex of inlets. Up to the right is a high chamber with further
climbs to a complex of oxbows and deserted streamways, At the end of
FUSION CHAMBER a tight crawl bypasses a boulder choke into a wide
arched passages with fine formations and false floors 
(care)
leading to HIROSHIMA CHAMBER. Just before the chamber is a short
passage up on the left to a 6m free climbable pitch past some jammed
flakes to a small stream trench amongst boulders. HIROSHIMA CHAMBER
has choked roof passages and an extensive bedding plane to the north
east where a tight 'L' shaped slot leads to an old inlet and the
inevitably choked boulder chamber. The chamber sits over some wet and
loose passages off the MAIN
DRAIN near ASSEMBLY HALL, and it is
reported that a vocal connection has been made through a very loose
and dangerous boulder choke.
