Lost Crusade, the 20 metre pitch in the floor of Indiana Highway, which bells out into an enormous shaft. The rope handline on the traverse over it is not really needed, and if this hole were not here, there would be no traverse line at all. But this hole is enough to make you grateful for a handline.

Looking out from the start of Canyon West. Ahead-left is the loop into Megadrive North. Ahead-right is the way out to Indiana Highway. Behind the tape on the right is the upper level opening into Canyon East. Canyon West is behind the camera.

-
Bat bones among the bobbly mud in Canyon West. The mud shows that this passage has been fossil since at least before the last ice age. The bat bones are presumably newer, probably a few thousand years old at most.
-
Guano piles in the undercuts of Canyon West.

-
The start of Canyon West is a series of oxbows and loops, with gorgeous, sculpted white rock ceiling. The easiest way through is to take a right at each junction, until the big guano pile.

-
More guano piles. These are much smaller than those in Raiders Passage, but still represent hundreds or thousands of years worth of bat droppings, using the same spot to hibernate over and over again.

Huge pile of guano in Canyon West, the largest guano pile in the UK. It is about 3 metres (10 feet) long in the longer direction, and 2 metres (6 feet) in the shorter direction. Pete is well over 6 foot tall, and is not a good choice of model for scale. The rift behind Pete has a vocal connection with the Raiders side passage. The way on here is to pass the guano pile, then take the passage on the left
Modelling by Pete, lighting by Tarquin and Pete
-
A heart-shaped sea of guano. This represents several thousand years of bat droppings. It sits on top of the bobbly mud, which means that the guano is more recent than the last ice age, under 10'000 years. It probably represents some of the first bat colonies to settle in Britain after the ice age. Judging from the clustering behaviour (the guano is only in discrete piles), these were likely to be greater horseshoe bats, which are now only rarely found at this end of the national park. We saw 2 on this trip, which are the first that I have ever seen in this cave.
-
After the guano pile, the passage loses some of its grandure.

-
Textured mud in Canyon West. This is fluffy/bobbly mud in ripples, created by ice, but probably moved into ripples by the water as the ice melted.
Lighting by Tarquin and Pete
-
A raised hagg (like a raised part of a peat bog) of guano.
-
A very different pile of grey guano. Perhaps this is a different species of bat, or perhaps it is much older guano. Or maybe it has been changed by chemical processes.
-
Start of Canyon East. The lower level is the usual way in, while the upper level is the connection with the start of Canyon West.

Canyon East is the more canyon-shaped passage.

-
Ctenacanthus dorsal spine in Canyon East. This is the bone that once held up the dorsal fin of a ctenacanthus proto-shark. It is far surpassed by those in Raiders Passage, but is still impressive.
-
The lower section is normally narrow, and that is usually where you walk. This is the widest part.

-
A much better dorsal spine, with gypsum crystals. The dorsal fin sat in the U-shaped cup on the right, with the front of the shark being on the left.
-
Wicking formations on the wall, created by the draught evaporating water that it wicked out of the rock.

Textured formation, that looks like it might have formed underwater.

Up above, there are some very wide sections, especially on the corners, but the upper ledges cannot be followed for long.

End of Canyon East.

-
The junction of Canyon East and Canyon West, where the passage takes on the combined size. For a while, it is possible to follow the upper ledges, but eventually, the canyon floor is the only way to make progress, occasionally climbing over fallen boulders. This is an unusual passage for Draenen, which has largely survived the ice shattering, and retained its original walls and ceiling, so progress is quite fast and relatively comfortable.

-
Grey guano near the junction.
-
The junction with Big Mole Passage, which takes some of the size away from the main Canyon. The junction is invisible from below, but can be clearly seen from the ledges. It is accessed via a slope from the bottom of the canyon.

Getting lower. The passage then becomes low enough that it could be considered a squeeze, and I continued alone.

Remains of a very dead bat in Big Mole Passage. This most likely died several years earlier.

The passage then shrinks and loses its charm, becoming narrow and muddy.
-
Remains of a dig at the end. This drag tray sits in a very awkward squeeze, on a 130° bend. There is not enough space for a normal sized person to turn around beyond it, so it has to be reversed feet first, into a narrow passage requiring a contortion manoeuvre to turn the corner. It took me three attempts to get back out, trying and failing to turn around in the tiny space beyond it each time. Whoever was digging this (Hades CC) must have been a very determined, small caver.
-
The dig, at the point where it is too small to turn around.
-
The dig continues as a flat out squeeze, rising up and heading into the unknown. I suspect that this may connect back up along Big Mole Passage since it points back along the passage, but if it is a way on, it probably would end up connecting to Going Square, rather than breaking new ground. It was too tight for me to contemplate squeezing onwards on my own to find out how far they had pushed it.
-
After the junction with Big Mole, the wide upper section of Canyon disappears, and the passage becomes a narrow canyon.

A climb up gains a very small side passage. Like most side passages here, it goes nowhere, and is probably just an incomplete oxbow.

-
Half way along, the passage turns a corner and enlarges. The draught, which had been blowing strongly along the passage, disappeared here. Roof tubes turned out to be only oxbows. The draught most likely sinks through the floor into Wooden Spoon Passage, which passes 25 metres below at this point. There is no known physical connection between the passages.

Guano at a corner.

The passage remains quite large for a little while, with a rocky floor, but quickly loses its grandure after this point.

-
The passage style finally changes completely at this junction. From here on, there are at least three routes, and it becomes very confusing. The main way to the end of the Canyon passage is through a narrow slot in the left wall just beyond Pete, then descending into the lower rift. The passage up to the left is difficult to reach and can be largely ignored. The low passage ahead is the way into the upper maze, and the usual route to Tractor Tracks.

-
The lower rift, which is quite narrow. It has a couple of roof holes up into various parts of the upper maze.

-
The junction where the different routes recombine, looking from the upper maze's final slope. The lower rift comes in from the left, continues ahead, then doubles back to the right.
Modelling by Pete, lighting by Tarquin and Pete
-
The way on passes an upper level oxbow, then splits into a multitude of little digs, with the furthest passage (seen here) never having been pushed. The passage here is 25 metres above the level of Crystal Mole and The Score (which would once have been connected), but without any obvious destination. It is not known whether there is potential here, but the passages must have drained somewhere.
Modelling by Pete, lighting by Tarquin and Pete
-
The passage to the upper maze starts as a crawl which quickly ascends to a higher level.
Modelling by Pete, lighting by Tarquin and Pete
-
The higher level. This soon passes over a hole into the lower rift, but confusingly, to return to the junction via that route, you would continue ahead in the lower rift, as it has doubled back before passing below.
Modelling by Pete, lighting by Tarquin and Pete
-
The main junction in the maze, with the way in being behind the camera to the left. On the left, a passage doubles back to become the upper passage at the junction before the maze. Up the unofficial rope is Tractor Tracks Passage. To the right is the way on through the maze. The ropes in this area are completely unnecessary, and not really strong enough to use for support. They get in the way, and should not be trusted.
Modelling by Pete, lighting by Tarquin and Pete
-
The way on through the maze. This passes over a climb down into the lower rift before splitting into tight rifts. The one on the right reaches the end junction with the lower rift.

-
The passage to the left at the main junction in the maze.

-
The rift ends abruptly at the junction before the maze, with a pitch down, or a very tricky climb down into the start of the lower rift. It is very easy to accidentally fall down it when trying to climb, so it is best avoided.
-
The start of Tractor Tracks, which is small and uninspiring.
Modelling by Pete, lighting by Tarquin and Pete
-
Tractor Tracks then passes through an awkward squeeze, and looks even less inspiring. Turning around in a tiny space to take this picture, it was looking like it might be another solo trip.

The passage then gains some very beautiful gypsum flower formations.

In fact, for most of its length, Tractor Tracks is walking sized, and very comfortable.

Shrinking back to stooping size. At this point, it passes over Far Agent Blorence, having completely crossed over the middle of the Round Trip.

The gypsum ends, and the passage becomes crawling sized. Sadly, it does not improve from here onwards.

-
Initially, the crawl is fairly comfortable, with scalloping suggesting that we are heading downstream.

-
Wider bedding section, where the only significant side passage is an oxbow.

-
A very low crawl then shows where the name Tractor Tracks comes from, with the central ridge and trenches either side looking like the ruts dug by tractor wheels.
Modelling by Pete, lighting by Tarquin and Pete
-
The passage briefly enlarges to standing size, the only significantly sized passage before the end. Perhaps there is another passage hiding under the floor here, because there is nothing good beyond here.
Modelling by Pete, lighting by Tarquin and Pete
-
A couple of dug out sections then reach the final tube.
-
The final tube seems to be in a different rock, without the sculpting. This appears to have been a lengthy dig, beyond the surveyed end of the passage. The dry stone walling and long drag rope shows that someone put in a considerable effort here.
Modelling by Tarquin's welly
-
The passage ends very abruptly indeed at a very definite, solidly packed wall. It looks more like a quarry than a dig, and does not appear to be an actual passage. There is not an obvious place to dig, even though it is the end of a reasonably sized tube. Quite disappointing. The passage has now reached Chocolate Blorenge (the downtream end of Far Agent Blorenge), but 35 metres higher. It is at the same height as Life On Mars, and was probably originally connected to that series, which would explain why both sets of passages are here.
