d. Sand, fluffy/bobbly mud and occasional angular rocks, in a large phreatic aven and a flat-out to walking-sized phreatic passage

f. Coincidental with gypsum snowdrifts. One very large lump which appears to be a gypsum geode-like-formation rather than a CCC. Between 320057,214131 and 319800,214404 from about 177 to 189 metres below the surface.

A couple of the patches were co-discovered by Pete Bolt.

There are doubtless many other places in the cave with similar deposits. It sounds like they may be in the Flyovers and Half Mile Passage area, but I have not yet had a chance to check those areas. It's a big cave.

Some of the deposits listed here may be decomposing gypsum crystals, but a great many appear to be CCCs. Time Machine failed to reveal any CCCs, but has other unusual white formations, which may be formed by condensing vapour containing calcite or gypsum.

Not sure about this set. I noticed them in my photograph of some unusual frosty spherical formations, and did not examine them in person. It is possible that the spherical formations are also cryogenic in origin (and perhaps also the selenite crystals, as they are often seen in conjunction with the fluffy mud).

a. Daren Cilau
b. Epocalypse Way, the area beyond Urchin Oxbow with giant selenite crystals and unusual frosty spherical formations
c. Aggregated clumps of yellow beads, coated in mud
d. Cracked, damp mud, selenite crystals and other unusual formations
e. Pictures attached
f. 320668,214479. Approximately 148 metres below surface.

a. Daren Cilau
b. Busman's Holiday, on the left side of the first piece of large passage after the long crawl beyond Bridge Cavern (heading towards Ogof Cnwc)
c. Very large white flat-sided yellow/white beads, small white beads and aggregations of white beads
d. Angular boulders in a large breakdown passage
e. Pictures attached
f. 320780,214980. Altitude not known, but should be approximately 100 metres below surface.

Very impressive set, with the large beads being about 2 cm in diameter.

a. Daren Cilau
b. Antler Passage, original terminal chamber with inlet choke leading to Busman's Holiday
c. Small white beads and aggregations, mashed into the mud floor
d. Mud on angular rock floor
e. Pictures attached
f. 320602,214984. Approximately 106 metres below surface.

Difficult to be certain with this set, due to it being immersed in a mud matrix, combined with multi-coloured gravel. It may just be white gravel, but in person, it appeared to be more likely to be cryogenic.
