By following one of the two routes from the end
of BILL TAYLOR'S PASSAGE,
taking care of the deep holes in the floor, the lip of Fall Pot
itself is reached, with the stream entering from COW POT far above. There are several ways down to the Master
Cave from here. The old fixed ladders installed in 1948 were removed
some years ago.
Up a mud slope at the
bottom leads down a short slope over boulders to a 12 m pitch
taking the water, whilst over to the left a descent down between
boulders (care needed) leads to the MASTER CAVE here some 3.7m
wide by 5m tall.
It lands close to the
base of the large fallen block mentioned above.
Routes 1, 2 and 4 unite in a mass of boulders.
The water descendes via a 12m pitch but a hole in the north-east
corner leads down through boulders to the Master Cave. Caution: this boulder route is loose and
dangerous after recent floods
Up the Main
Drain from here leads to STAKE
POT and the rest of the Ease Gill
System, whilst just upstream on the right is the small inlet at the
start of WOODHOUSE WAY
Up the Boulder slope from half way down Fall Pot leads to the continuation of Montagu East Passage and the HIGH LEVEL ROUTE through to Stake Pot.
Downstream the passage skirts the boulder pile in Fall Pot, enlarging suddenly into a tall rift.

Just 20 m down the Main Drain from Fall Pot on the right hand side at floor level is a low arch leading into Burgess' Passage, The start of AARDVARK COUNTRY. This is followed almost immediately by an 8 metre ascending pitch. A short section of passage leads to two 3m climbs and a 30 m section of rift passage to a chamber with apparently three ways on in the roof. The right hand branch 10 m up in the roof is only a blind pocket and the inlet is too tight at the top, but the left hand aven is scalable for 8m to a series of sandy crawls.
To the left a tunnel leads back towards the Main Drain and ends in two sandy digs. To the right a larger passage heads under a false floor until it lowers to a junction. The right continues low for over 30 m to a mud and calcite choke and is close to Montagu West Passage. Just before the end a there is deep rift in the floor with the sound of the Master Cave coming up it.
Right at the junction is Keyhole Passage an awkward narrow meandering tube. At the end of this is a 3 m free climb onto a balcony, The Pulpit. This is followed immediately by a 10 m pitch down into a large spray lashed chamber. The inlet in the roof is a 13m pitch from a passage in the floor of Shale Cavern in the entrance series of COW POT. From the base of the chamber a 16m wet pitch lands on a ledge below which is a water filled rift. From the ledge a passage can also be followed to a further 5m pitch into a system of narrow rifts back at the same level as the Lancaster Hole sump.
Seventy metres further downstream beyond
Burgess's Passage lies the entrance to WILF TAYLOR'S
PASSAGE. Just upstream of this on the
true right bank is a small passage. it goes for about 30 metres past
a small sump to a mud choke.Twenty metres further downstream beyond
Wilf Taylor's is the large slope up into WATERFALL
PASSAGE at a sharp left hand bend.
Ahead is a long straight passage with a steadily lowering roof and a
deepening canal to the final downstream sump 81m below Lancaster Hole
entrance. 
THE SUMP. The initial investigations here failed to find a way on, however, 25m from base a large pebble-floored bedding at -11m depth leads off on the right hand side of the sump pool. From here a passage averaging 1m high and 7m wide continues to 142m from base. Here the roof and walls disappear as the passage enters a huge underwater chamber containing a steep slope of debris. A rift in the roof here has been ascended to -1.5m depth and following the spectacular underwater ramp down straight ahead ends at a narrow rift at -28m depth. However, a route to the right at -15m depth descends to the bottom of the slope to enter a magnificent scalloped tunnel (The Metro) at -32m depth. This large passage heads generally south south west and by following the right hand wall leads over a cobbled floor until the depth gradually decreases to -31m at 275m from base. The route ahead continues in a passage at least 5m wide and 3m high (and often much larger) and passes numerous whalebacks of pebbles, the depth varying between -30 m and -32m. An excursion into the roof at 425m attained a depth of -21m but the roof was still out of sight. The large passage continues to the present limit of exploration at 650m from base and -29m depth. Here the passage is 9m wide and 5m high. This point is 220m from the furthest explored upstream limit in Leck Beck Head and 300m from the resurgence at Witches Caves
