This was a visit to learn the Crystal Inlet area, and the Flyovers-Half Mile area of the cave. These are not shown correctly on the 1991 survey, and appear to be described incorrectly in the Chelsea Spelæological Society's "An Exploration Journal Of Llangattwg Mountain" - one of the only publications to include a description of the area. Part of the mistakes appear to be due to early exploration notes referring to Crystal Oxbow as a "climb up to a high level passage" and then other notes confusing Crystal Oxbow as a branch of Crystal Inlet, and claiming that it ends in a choke, which it doesn't. A subsequent trip then picked up the remaining passages around Beyond Time
Unless we missed something (which is possible), Crystal Inlet leads upstream for 50 metres, to where the water comes from a narrow passage on the right, which is the way on along Crystal Inlet (this is the point mentioned as a branch or Y-junction). The obvious passage ahead, which does not need you to climb up to reach it, is Crystal Oxbow. Crystal Inlet is narrow and sometimes awkward, ending at a very tight section after 200 metres. After just over 100 metres, there is a climb up into a short side passage on the right. Crystal Oxbow contains many fine crystal pools, gypsum crystals, and intricate helictite formations, reaching a chamber after 150 metres. The chamber has two avens which both enter Nameless Canyon and Half Mile Passage - the aven ahead can be climbed with the assistance of a handline. In the chamber, right closes down, ahead-left is a drop down behind rocks into Crystal Corridor, while left is the continuation of Crystal Oxbow, soon reaching a taped-off drop back into Bonsai Streamway. Crystal Corridor is a narrow, scalloped rift passage, starting as a crawl, soon becomming walking size, then returning to crawling sized, passing a short side passage on the left. After 100 metres, it reaches a drop down into Bonsai Streamway. The first part can be free climbed down to a passage on the right which quickly reaches Beyond Time. The second part of the drop down reaches Bonsai Streamway, and can be free climbed with difficulty too, but equipment may be desired.

A tricky climb into an oxbow after the entrance crawl, which bypasses a mud-filled section. This often proves tricky for shorter cavers.

Big Chamber Nowhere Near The Entrance (named as a humorous reference to Big Chamber Near The Entrance in Ogof Ffynnon Ddu). The archway on the left is Jigsaw Passage (the way in), while Gareth's light is shining into Epocalypse Way (the way towards the Ogof Cnwc through trip). Up the boulder slope on the right is the rest of Big Chamber, and the way on to the downstream cave. Behind the camera is a blind alcove. The logbook sits on the boulders between Epocalypse Way and the slope up.

You know you have found Eglwys Passage when you see this traverse. Then follow it through some crawls, ignoring side passages.

Looking back out of Fiveways Chamber in Eglwys Passage, where the way on is into an eyehole on the right (seen on the left here, with the chamber's entrance being ahead-right). This is a key junction for the route into the downstream cave.
Modelling by Gareth, lighting by Tarquin and Gareth
-
The eyehole is almost comically small, requiring a hands-first dive through the hole. Though not a squeeze, this is the size limitation for equipment being taken into the cave, as it only just allows the 15 litre Daren drums to be taken in for food storage at the camps. Even though The Vice is narrower, it is much taller, so it allows wide equipment to be taken through vertically; this hole does not.

A short crawl - the 1985 breakthrough point - then emerges in St. Valentines Chamber. Loop Route's choke lies under the floor to the left, while the way on is down through the choke in the floor at the lowest point.

Climbing up The 60, a 20 metre pitch into Higher Things. The 60 has a flexible ladder, rigged with the rungs upside down so that they pinch your feet, wrapped around the rocks on a diagonal slant at the ledge. It almost always invokes bemused laughter from visitors who have not seen it before.

Crazy collection of mud sculptures made by bored cavers waiting for their turn at the top. A caving hut, mushroom farm, animals of all kinds (the cobra is particularly nice), the obligatory penises, gnomes, beer mugs, caving helmets, and countless other trinkets.

The crawl then reaches this larger rift. That little line of rocks on the floor is a warning - don't go this way, there is a very deep hole down into the large passage far below.
-
In the other direction, a climb down a rope reaches another oxbow level, with yet more holes dropping down.

-
In the safer direction, the passage rapidly grows, and drops into the side of White Passage, via a couple of roped climbs.

The ropes might not be needed on this climb, but they definitely make it much easier.

The Time Machine is currently the largest known passage in the UK, though some parts of Draenen are very close to this size as well. While impressive, it does not feel as big as it might seem, since it is much lower than similarly sized passages in Draenen. Later on, however, the passage does become taller, but becomes narrower instead.

We now begin our first excursion, heading into Crystal Inlet. The initial passage is quite large and inviting, but the stream soon cascades out of a small side passage instead.

Fractured stal. This appears to be a possible example of ice-age ice fracturing, as each old stalactite was broken off at the same height.
-
The newer flowstone on the floor has superb helictites. The mud splatters here can be clearly seen to affect only the flowstone, but not the helictites. This makes it very clear that the mud splatter is historical, predating the growth of the helictites. It looks like human influence, but it is natural. Interestingly though, the flowstone has not grown since whatever event created the mud splatter, with the exception of the helictites.

Now near the end of Crystal Oxbow. The ramp in the distance is the floor of the chamber with the avens. The passage has changed shape to a smooth arch with a triangular cleft in the ceiling.

-
Not to be outdone, the passage puts on a final display, with this incredible formation of stacked calcite rafts in a dried crystal pool. This is almost (but not quite) as good as the Snow Gardens in Slaughter Stream Cave - it is just missing the central pool.

Unfortunately, it soon becomes crawling sized, and we decided not to continue to the junction with Beyond Time.

When trying to turn around to retreat back to more interesting passages, it quickly became apparent that some methods work better than others. Gareth tried trapping himself into Buddha pose, but it proved not to be a comfortable technique for turning. Who knew?
Modelling by Gareth, lighting by Tarquin and Gareth
-
From the junction with Crystal Oxbow, Crystal Inlet is much smaller, and much more slippery. Several little cascades add to the fun, but the passage has no other attractions.
Modelling by Gareth, lighting by Tarquin and Gareth
-
The widest part of the passage is this plunge pool. Some of the other pools require traversing to avoid swimming.
Modelling by Gareth, lighting by Tarquin and Gareth
-
After a traverse over a tight rift, the inlet then becomes very narrow, and only a very determined caver would want to continue. Gareth tried descending to stream level to force a way up the passage.
Modelling by Gareth, lighting by Tarquin and Gareth
-
The passage has in fact been forced at floor level for 35 metres, to reach a flake which blocks progress. Gareth gave it a good effort, but reversing through a 35 metre squeeze doesn't sound as much fun as visiting the Flyovers, so he was encouraged to return early.

Then a very impressive spread, strewn in patches across the floor. Most of it sits on sand, not fluffy/bobbly mud or breakdown, and the passage is a clean phreas, so it seems like the wrong place to find it. But here it is anyway.
Modelling by Gareth, lighting by Tarquin and Gareth
-
Most of the cryostal is bead aggregations. They can be seen to form bands of more and less dense clusters of beads.

Then a very large group of giant cryostal clusters are seen on a pile of rocks. It is possible that they were moved here to keep them away from feet.
-
These are some of the largest pieces in the cave, and some of the best looking pieces in any British cave, competing with those in Draenen. This is the largest cluster of giant pieces that I know of, around 20 cm long and wide, with the largest pieces being about the size of a karabiner.
-
After that is a series of pieces of cryostal which seem to be mixed with sand, probably after meltwater washed it over them.
-
This piece is the single largest cluster I have seen in any cave, around 14 cm long in its longer direction.
-
Seen here with a hand for scale, it is almost ridiculous.

More sand-covered cryostal. This is a particularly large piece. The flat part looks like a possible footprint, or maybe a rock print.
-
A final piece of cryostal - this is the last significant piece in Western Flyover.
-
Western Flyover has been the site of a camp. Though I fail to see why, since Hard Rock is very close, and much more comfortable, even with its own flushing toilet. This camp has no toilet. But sleeping on sand is comfortable, even if it does get everywhere. Gareth is demonstrating with a camp (or at least limp wristed) sand dance.

Originally, the roof tubes were used to reach the final part of the passage, but a sand swim under the wall reaches the same place more easily. This is a tight squeeze, but don't worry; you can always enlarge it if it is too small for you.

A final very impressive section of passage. They missed a trick here; it really should have been called West End.

The grotto's stal is not exactly natural, being moulded out of mud by bored cavers. I guess it helps to liven up a dig.

From the balcony, a 4 metre ladder leads to an upper passage. This could be free climbed, but the ladder certainly makes it easier.

The southerly traverse. This has a rope to assist, but the rope ends at the most tricky point, and doesn't really serve the purpose very well. The hole is 6 metres deep, with only a dig below.
Modelling by Gareth, lighting by Tarquin and Gareth
-
The side passage immediately afterwards ends at a boulder choke. At first, this equipment seems bizarrely out of place. It is used to tie the cable around boulders, and then pull them out of the choke from a safe distance. This choke sits directly beside the top of the choke in Eastern Flyover, and could possibly be a place to bypass it. Half Mile Passage loses its grandure at this point, and appears to become a series of soakaways, which suggests that the water is simply trying to drop into the Eastern Flyover old main drain.

Finally, there is this traverse over a deep hole, dropping about 10 metres into Crystal Oxbow. This is one of the two avens in the chamber in Crystal Oxbow - the one that cannot be free climbed. The passage on the other side is Nameless Canyon - even though it is really the continuation of Half Mile Passage - which has another hole down to the left almost immediately, which is the second aven. That hole can be climbed with the rope that was in place.

Nameless Canyon (which is also called No-Name Canyon, so it has 2 names...) then pops into the side of a larger, sandy passage, which is also called Nameless Canyon (just accept it, OK). Left closes down, but right continues like this.

The crawl seemed to go on a very long way, so since we were running low on time, we decided to leave it for another day. The survey makes it look like it might enter a short section of larger passage before it ends. It does not point in a useful direction, and probably is just an oxbow.

To the right are two short passages, the left of which pinches out just before connecting with the other passage.

It seems a little out of place with so much gypsum around it, but the beads show that this is definitely cryostal.

The phreatic tubes are rather attractive, with white gypsum coatings and obvious scallops. They end rather abruptly at mud infill, with a tapping connection to Painkiller Passage. This connection has intentionally been left closed, since it helps to preserve the formations in that passage.

-
In the floor pit of Boulder Chamber, an alcove on the side offers the other way on, decorated with iron-stained rocks.
-
In the floor is a hole down to Bonsai Streamway. It is possible to free climb below the camera (on the near side of the wedged boulders), using some ledges, but it looks quite tricky, and equipment may be preferred.
-
Above the hole down, a climb to the left gains a small tube, which drops into the end of Crystal Corridor. It is just as small and uninspiring at this end.
-
Returning to The Meeting Room, the left-hand way to the Time Machine starts promising.
Modelling by Claire, lighting by Tarquin and Claire

However, it ends at a choke, just after passing over this deep hole into the Time Machine. It looks about 25-30 metres down, and is not free climbable.

Looking out into the southern end of the Time Machine, with the floor level reached via a short climb. Amazingly, the enormous passage we are in is almost invisible from below the climb, and can be easily missed when walking past, even when looking for it. From below, it just appears to be an alcove in the roof. With the final loop now completed, we headed out.
