27th December 2018: with Roz, Brockers, Nick, Tav and Jon.

Had purchased some supplies and a good team assembled to help carry the equipment, including drill bag, sundries bag, drill-bit tube, wire and a 3.5m aluminium ladder, into the cave. There was some debate regarding the length of the ladder, so Brockers carried in a hacksaw, just in case. A careful trip through Chamber 20 to the sand dig where there was plenty of evidence for recent slumping.

With a bit of jiggling the ladder was installed and I was able to drill 4no. holes into the slab of rock. Brockers passing various bits of kit and stuff as and when required. The rest of the team spent time sorting out the spoil heap and ran-out the wire. The holes were charged, and the evening brought to a satisfactory conclusion from a safe location.

23rd December: Spur and furrow morphology at Sandy Bay, North Somerset.

The spurs comprise silts and clay with some sand, the base of the furrows being lined by a coarse pebble/fine cobble layer, which could be an underlying sediment or a lag deposit dragged into the furrows by the tide.

Swallow Cliff Bay drift sequence. The most complete exposure is found in the south-eastern corner of the bay (right-side of image) where it rests on the fossil shore platform, here it is cut into [Carboniferous] basaltic lava at about 12.5 m OD.

6th December 2018: With Duncan, Jonathon,
Nick, Tav and Alex

The trip through Chamber 20
didn’t appear to be much wetter than last week, in spite of the recent rain. At
the sand dig, the water level had risen c.150-200mm and was encroaching into
the alcove. Everything at the bottom of the dig was slippery, the self-digging
hadn’t occurred, and the large, precarious slab of rack was still overhead.
After some protracted discussion, it was decided that the rock needs to be
dealt with before digging can continue [relatively] safely, some chemical
persuasion is required, it will be done!

Tav suggested that we
might re-locate the retaining wall and so create extra spoil dumping space,
this seemed a good idea so, that’s what we did for the evening.

I had a less than
comfortable trip out of the cave, the sole of my boot had decided to become
detached and go solo, one moccasin is not great for caving – or one socked foot

29th November 2018: Last weeks digging
session was abandoned for the pub when only three of us turned up at Wookey

Better turn-out this
week, with Nick, Tav, Jonathon, Duncan, Mike and, course yours truly, all keen
and raring to go, unfortunately Roz got left behind and wasn’t happy about it!

After some persistent wet
weather recently, we weren’t all that hopeful about this evening’s prospects
but, we headed off anyway. The cave was active, the sound and sight of
dripping, running water all the way up through Chamber 20. At the sand dig, the
anticipated puddle of water but, rather surprisingly, not as deep as expected.
The excavation had become
self-digging as more had slumped from the roof to reveal a space overhead,
which was encouraging, and potential lead(s). Some digging was possible but
continual slumping and a large, suspect slab overhead soon put an end to it. That
was, until Nick decided to poke a bar into the bottom of a small pool of water
that became a flow of water and a pile of sloppy sediment. After some more
interventions, more slumps, and time running-out, we decided to leave it to
settle down, perhaps continue to self-digging and return next week. hopefully,
the water will continue to drain freely, and wet conditions will not impede
further progress too much.

To the pub!

15th November 2018: with Jonathon, Mike, Nick and Alex

Surprisingly, the sand
dig was dry and didn’t appear to have backed-up at all after the very heavy
rain last weekend. However. A seepage of water through the sediments in the
alcove had caused some slumping and work was concentrated there to tidy-up and
consolidate. The trickle of water that enters from the chamber was constant,
making the steps slippery so these were tidied up too, very sloppy spoil. The water
from the trickle is draining freely through the sandy sediment at the bottom of
the dig.

Alex and Nick shared the
digging, Mike loaded the filled buckets into the skip, Jon hauled the skip up
the slope and I emptied the buckets. The process was, of course, repeated many

8th November 2018: with Alex, Mike, Jonathon
and Roz

It’s been raining
recently and all the way up through Chamber 20 the results of this were clear;
the drips were stronger, pools were filling-up and water was flowing down the
calcite cascade. However, on arrival at the sand dig, we were pleasantly
surprised to find it bone dry and no signs of water having flowed into it, this
despite the small tube being full and overflowing.

Alex climbed down into
the pit and began digging in the alcove, I was moving the filled buckets and
passing them up to Mike, who then placed the filled buckets into the skip,
hauled by Jonathon, Roz was in control of spoil dispersal. The empty buckets
were returned, the process repeated, many times.

In between moving buckets,
I spent a little bit of time tidying-up a section of the sediment bank where
evidence of flooding and subsequent draining events is clear. It really needs
more time spent on it and a full section cleaned and recorded.

All too soon it was
time to move the tools to higher ground, just in case, and depart the cave.

25th October 2018

With Alex, Nick,
Jonathon, Mike, Duncan and David Walker (curator at the Wells & Mendip
Museum and MCRA)

At the sand dig we were
relieved to see it had dried-up and quite quickly after the fill event by the
look of it. I started to dig in the [dry] alcove, because I got there first,
Alex reduced a limestone boulder in size and removed the slop from the lowest
point of the dig. The spoil management team were not impressed with the slop
and were experiencing some difficulty in extricating it from the bucket. The
solution, they decided, was to put a couple of handfuls of drier sediment into
the bucket first, the diggers, of course, complied with this instruction.

Nick was on the steps
passing the filled buckets to David, loading the skip to the spoil management
team comprising Jon, Mike and Duncan.

When Alex had removed the
slop, he turned his attention to clearing the loose sediment that I was
creating in the alcove. The buckets started to move freely at a good constant
rate. There are some very interesting layers of deposition to look at in the
sediment bank, these can become, somewhat, of a distraction. Flood events and
subsequent drying periods can be clearly distinguished.

All too soon it was time
to stop digging, clear the loose, stash the tools at a safe height and make our
way out of the cave. Changed in the car park and up to the Hunter’s for well-earned

18th October 2018

With (l to r) Mike, Duncan, Nick and Tav

After persistent rain
last weekend, it was not a surprise to find that the trip through Chamber 20
was wetter, the calcite cascade had water flowing down it. As suspected the sand
dig was had about a metre of water at the bottom and there was still a trickle
of water flowing into it, as such, it was undiggable. There were a few rocks in
a vulnerable position, if a slump-in occurred they might end up at the bottom
of the dig. So, these were moved and the spoil retaining wall was extended.
We were in the Hunter’s a
bit earlier than usual. At least the forecast is for dry weather for the next
few days, so the dig might drain. Unfortunately, it will not take much rain to
refill it though.

With Nick, Mike,
Jonathon, Tav, Alex and Duncan

Nick, Mike and Jonathon
at the sharp end, digging and filling buckets, then moving the filled buckets
and occasional rocks to Tav who then facilitated dispatch. Alex hauling the
loaded skip and passing buckets and rocks to Duncan. The buckets were emptied
onto the spoil heap where I was on spoil management duties. It was a pleasant
evening with the usual banter and a lot of sediment was shifted. The dig goes

We were joined, for a
while by a large [queen] wasp. It was noted too, that the cave was slowly
becoming wetter, previously dry pools now have water in them.
