<p>The final Pitch of the Apocalypse lands in a chamber floored with boulders,
with one huge block in the centre. Around 5m off the ground, it is possible to
swing off onto a ledge, where a hole in the wall reveals a sporting passage
which spirals down steeply in a corkscrew pattern, passing several short climbs
and a tight bend (requiring SRT kit removal, at least if you're as fat as
Dave). Beyond this the passage appears to close down, although there are one or
two unexplored side branches [<ahref="qm.html#C2005-204-59"id="qC2005-204-59">C2005-204-59 C</a>], and the passage has not been
surveyed.</p>
<p>The continuation of the pitch series is <b>Mornington Crescent</b> [NIAL]

drop belayed off a spike lands on a wide ledge. <i>Traversing to the right
leads to a steep upward slope, at the top of which a passage leads
right and left; to the left is [<ahref="qm.html#C2005-204-50"id="qC2005-204-50">C2005-204-50 C</a>] and to the right is [<ahref="qm.html#C2005-204-49"id="qC2005-204-49">C2005-204-49 B</a>] (the
latter has an 11-second rattle).</i> Traversing leftwards reaches a
short pitch into the spacious, boulder-floored <b><aid="turnstile">Turnstile
Chamber</a></b>. An aven enters to one side [<ahref="qm.html#C2005-204-51"id="qC2005-204-51">C2005-204-51 X</a>] while
continuing on leads to a funnel-shaped hole in the floor. This is rigged with a
Y-hang from a pillar and a spit, and a deviation to the other wall, but this
requires some athletic manouvres to pass. The pitch is only 5m deep and lands
in another large chamber. (The pitch can be bypassed by a climb down through
the boulders, but this is not recommended, as the boulders are not especially
stable.). <i>[XXX This is as far as I ever went and everything else here is
solely based on the survey! XXX]</i></p>
<p>In this next chamber <i>which I propose be called The Platform</i>, a climb-up the right-hand wall leads to an unpushed crawl [<ahref="qm.html#C2005-204-52"id="qC2005-204-52">C2005-204-52 A</a>], while straight on leads down a couple of minor pitches past another passage on the right [<ahref="qm.html#C2005-204-53"id="qC2005-204-53">C2005-204-53 B</a>] to a 9m pitch. This lands in a wide passage, <b><aid="thetube">The Tube</a></b>. There is a hole in the floor [<ahref="qm.html#C2005-204-54"id="qC2005-204-54">C2005-204-54 C</a>] while the passage continues both north and south.</p>

<i>The largest of these holes was descended for 25m through a wide chamber
(<b><aid="morden">Morden</a></b>) to a narrow twisty passage. After a
further drop of 16m this narrows somewhat, but more rift is visible
beyond [<ahref="qm.html#C2005-204-46"id="qC2005-204-46">C2005-204-46 C</a>].</i>. Continuing along Tooting Bec leads past yet more

passage on the left; continuing straight along this ends, but turning right
partway along leads to another steep upwards ramp, with a slimy muddy floor. At
the top of this is a fork; the right branch is [<ahref="qm.html#C2005-204-33"id="qC2005-204-33">C2005-204-33 B</a>] which probably links to
05-34, while the left branch continues, sloping steeply up; a handline is
<p>Heading southwards from the pitch into The Tube, the passage passes under an aven [<ahref="qm.html#C2005-204-55"id="qC2005-204-55">C2005-204-55 X</a>] soon reaches a complex junction, <b><aid="stpancras">St. Pancras</a></b>.

To the left is a pitch, <b><aid="pigsear">Pig's Ear Pitch</a></b>, which can be either descended or traversed round.
<i>Traversing across leads to an upward-sloping passage, <b><aid="dlr">Docklands Light Railway</a></b>. At the top of this is a pitch [<ahref="qm.html#C2005-204-26"id="qC2005-204-26">C2005-204-26 A</a>], with a passage visible across the pitch-head [<ahref="qm.html#C2005-204-27"id="qC2005-204-27">C2005-204-27 B</a>].

<p>Descending Pig's Ear Pitch from St. Pancras leads to the Picadilly Line, a
very wide, boulder-floored passage. This slopes downward, passing an aven
[<ahref="qm.html#C2005-204-25"id="qC2005-204-25">C2005-204-25 X</a>]. Beyond this is a junction, with another aven [<ahref="qm.html#C2005-204-24"id="qC2005-204-24">C2005-204-24 X</a>] above it. On the
left is a narrower passage leading to <ahref="#greenpark">Green Park</a>,
while ahead Picadilly Line continues, still sloping downwards. After around 50m
it narrows and swings to the left, passing a passage [<ahref="qm.html#C2005-204-23"id="qC2005-204-23">C2005-204-23 B</a>] on the left. This
final section carries a trickle of water in a trench in the floor. At the end
of the passage this disappears down a hole in the floor [<ahref="qm.html#C2005-204-22"id="qC2005-204-22">C2005-204-22 B</a>], beyond which
is a 10m pitch, <b><aid="dogsdinner">Dog's Dinner</a></b>, with very poor
quality rock. This lands in a large chamber, <b><a
id="hounslow">Hounslow</a></b>, with a boulder floor. Above is an aven [<ahref="qm.html#C2005-204-20"id="qC2005-204-20">C2005-204-20 X</a>].
In the floor are two more holes. The smaller is [<ahref="qm.html#C2005-204-21"id="qC2005-204-21">C2005-204-21 B</a>], while the larger leads
to a 24m pitch, <b><aid="dogsbollocks">Dog's Bollocks</a></b>. The water
rejoins part-way down, and at the bottom is a sump, at a depth of 490m from
204e.</p>
<h3>Green Park and the Jubilee Line Extension</h3>
<p>From the junction in Picadilly Line, an upward-sloping side passage leads
off. This passes a 2m climb to a juction, <b><aid="greenpark">Green
Park</a></b>. Straight ahead the passage continues for a few metres between
large mud banks, but the main route doubles back over itself and emerges in
another passage, <b><aid="jubilee">Jubilee Line Extension</a></b>, which runs
for around 50m parallel to and more or less directly above the Picadilly Line.

passage continuing in both directions [<ahref="qm.html#C2005-204-29"id="qC2005-204-29">C2005-204-29 A</a>] [<ahref="qm.html#C2005-204-30"id="qC2005-204-30">C2005-204-30 B</a>].</p>
