When I mentioned the bad air in Cuckcoo could be worse since the new lid was fitted I was told the CSCC were organising some CO2 testing. Did they ever do it?
My suggestion was to cut a slot or hole in the lid to allow some movement of air.
Tynings has a similar problem and also has a lid with no ventilation hole.

What have we to loose by having a hole in the lid?

Last week was high atmospheric pressure which does back up the theory about the bad air occuring at such times.

Honeymead Hole - Maesbury, Shepton Mallet.

An MNRC trip last weekend (16 August 2009) encountered very high levels of CO2 in the cave.

Several in the party felt ill and one is still not too good 24 hours later.

The following anchors in Rhino Rift have been reported defective and are under investigation by CSCC:
RR-FP-08  Rebelay on first pitch
RR-SP-01  First anchor on traverse line to second pitch

CSCC is investigating this report and you will be notified again when a CSCC appointed person has inspected the anchor and a decision has been made on what, if any, remedial action is required.

Please note: the CSCC does not carry out any routine inspection or testing of bolts within the CSCC Anchor Placement Scheme. This policy is in line with the BCA statement on the testing of anchors.
Further, the CSCC view is that individual cavers should satisfy themselves that the anchors they are proposing to use are safe.

The following anchors in Rhino Rift have been replaced:
     First anchor on the traverse line to the second pitch
     Two anchors of the second y hang on the second pitch

All anchors on the first and second pitches have been inspected and although in some cases the rock resin bond has started to fail, as can be seen from the slight rotation (less than 1mm),  it is my opinion and that of others in the working party that they are safe to use and do not require immediate replacement.  The anchors where the rock resin bond is starting to fail have been identified for future replacement.

Please note: the CSCC does not carry out any routine inspection or testing of bolts within the CSCC Anchor Placement Scheme. This policy is in line with the BCA statement on the testing of anchors.
Further, the CSCC view is that individual cavers should satisfy themselves that the anchors they are proposing to use are safe.

The proposed chain on the head of the first pitch has not yet been fitted.  A suitable vendor has been identified and I will update here when the chain is in place.

Has the proposed chain at the head of the first pitch
been fitted yet?

The air in Cuckoo is again not good with high levels of CO2 = typical for this time of year.
The winter is obviously the best time to visit this cave.

Some other Mendip caves know for bad air are probably also affected.
The CSCC web site contains some useful information:

Rhino Rift, Loose rocks- top of Third Pitch.
« Reply #37 on: August 28, 2011, 08:51:03 am »
Rhino Rift

There have been reports about instability of the boulders that make up the top of the third pitch. The pitch head appears unstable and it is advised that you take great care here and better still don't use the direct hang but instead use the “Right Hand Route” third pitch. Do not congregate below this area and be aware that it is possible (probable) that any further collapse here could (would) block the way on (or out) from the rest of the lower cave.

Rhino Rift Again

The boulders at the top of the third pitch have moved. Several have fallen down the pitch, including one of about 4 Tonnes! There are still boulders perched precariously at the pitch head, including one extremely large boulder that appears to have no visible means of support. You are advised to avoid going below the top of the third pitch and also to stay away from the pitch head. Although the “Right Hand Route” will avoid the instability, you wouldn't want to be below the top of Pitch 3 at the moment. It is almost certain that the way on to the rest of the lower cave is currently blocked.

It is planned to leave the pitch head alone for the winter to see if it stabalises or otherwise, so you are advised to restrict any caving to the first two pitches for now.

Tynings Swallet 19/09/2012

Has anyone been down Tynings recently and noticed bad air? 

Very short trip yesterday down Tynings.  Appeared to be traces of bad air throughout the cave.  Stopped at top of Pyramid Pot to get breath back... which took far too long. 

On return air very bad round the chamber before Pyramid Pot.

High CO2 is quite common in Tynings. Especially in the late summer (when everything is growing)...

East Twin - Collapse of boulders in roof of Spar Pot connection

During the heavy rain 2 weeks ago, mud/grave infil was washed out of the Spar Pot connection, followed a week later by a collapse of the boulders in the roof of the small chamber before you squeeze through into main rift in Spar. Hopefully the extent of collapse is small, but there is a large boulder choke just beyond.
There are also a couple of vicious looking flakes still wedged but only just, we will bring these down next week and assess what has moved, what hasn't.
For a few weeks at least, consider Spar Pot too dangerous.

Had a very tiring trip to the bottom of Tynings yesterday (05/05/13) with numerous stops on the way out to catch our breath.  I suspect the CO2 levels are quite high throughout the whole cave as we didn't notice any significant improvements until back at the entrance.  Unless we get a repeat of last summers weather things are only going to get worse down there over the next few months.

Very high levels of Co2 in Manor Farm today 15/12/2013, would advise people to avoid passing Alberts Eye - very large amount of Farm waste entering the cave at the aven near fleet street.

Anyone else think the bolts on the 20 in Swildon's are getting a bit loose?  Might be worth a look with an expert eye

Drunkard's Hole. The girdered and cemented rock pile at the bottom of the tight chimney, before the pitch, appears to be suffering from some undermining due to the smaller debris falling away. Some of the downslope pile looked a bit precarious when we were there midweek, with several slippages occurring during the time it took to rig the pitch. This area would benefit from some consolidation with cement.

Noticeably poor air (probably around 2%) in PP. Mild exertion resulting in prolonged breathlessness.

November 8th-9th 2014:


Particularly bad air conditions reported in both Tynings Barrow Swallet & also Manor Farm Swallet during the weekend with aborted/altered trips resulting.
