WARNING
The 34 m shaft 
is narrow at the top but
soon opens out to large dimensions, passing two ledges to reach a
boulder floor. There are three ways on. To the S.E. leads up a climb
to SLUG
WORLD. A slot in the floor leads to the
Girder Route to Kath's Way. RRCPC Newsletter. Vol. 36 No.
3 Article 1. Nov. 1999. Finding the "Way-On" A Historical Note from Kathie Gilbert
To the S.W. is the main way on. A step up leads
into a large rift passage 
with a slot in the floor
and a short walk emerges at the top of the steep boulder slope down
into Bridge Hall. 
Immediately on the left are two routes into SAND
CAVERN Series, both of which unite at a 7 m climb. The Sand Caverns
route continues below this pitch through a series of sandy chambers
and crawls to a choke, which draughts. On the left in the penultimate
chamber is a squeeze and a very tight connection to THE CRATER.
Slightly further down the steep boulder slope mentioned above, and also on the left, is the concealed crawl which leads to THE GRAVEYARD SERIES
By continuing down the slope into the chamber,
passing a hole down through boulders at the lowest point, (Kath's
Way) a mud slope can be climbed on the right to a blind 6 m pitch,
Barker's Pot, which can be bypassed via a crawl at half way up the
slope. To the left at the bottom of the slope an easy climb up
and traverse round to the right enters a large passage. This closes
down to a short crawl which enters the Colonnade Chamber 
with its beautiful
columns. See first photo
taken in Lancaster Hole by Eli
Simson. At the far end of the chamber
the way swings to the right and narrows to a rift which quickly
chokes, as does the high level route reached by a 8 m climb.
Back in Bridge Hall the hole in the boulders drops into Kath's Way, at the bottom of the drop a low crawl is reached, with a branch off to the right into The Girder Route connecting with Sand Caverns via 7 metre pitch and also with the slot in the floor at the bottom of the Entrance Pitch.
The main route on, Bill Taylor's Passage,
enlarges to an alcove on the left where a showerbath enters, and just
beyond, a couple of holes to the right lead to
THE CRATER. A descent of the largest enters a
squeeze to a sump which can be bailed. Beyond a small passage leads
to a climb into a larger section and a 19 m pitch into the Master
Cave just upstream of the downstream sump. A low crawl continues over
the pitch for 91 m to another small sump. This has recently been
pumped out but gets too constricted. Carrying on over the top of the
Crater there is a small maze of passages with a tight connection
through to the end of Sand
Caverns
Back in Bill Taylor's Passage 
the way on enlarges
considerably and then splits into two, both ways unite in the
vastness of Montague West 
Passage where it
encounters FALL POT.
If the left hand route is taken, a descent of
several small steps leads to a cleft in the floor which is the 20 m
pitch into the Master Cave.
A careful traverse right here up a mud slope
leads to a parallel passage to FALL
POT. and an alternative descent
via a traverse of Fall
Pot
A careful traverse round to the left here, on a sloping mud floored shelf, leads to the start of MONTAGU WEST PASSAGE. Leading to Wilf Taylor's and Waterfall Passages, two separate routes down to the Master Cave and Downstream Sump.
Fork Handles Series
This leads off via an inlet half way along BILL TAYLOR'S on the north side. it is a series of scaled pitches of 12m, 8m 12m and 7m ascending 40 metres to a bedding in a shale band.with a too tight inlet.
