Hallowe'en Rift, Mendip Hills

Excursions [and other notes] involved in the exploration of Hallowe'en Rift; a cave, so far, formed within Triassic Dolomitic Conglomerate.

The exploration of Hallowe'en Rift was started in 1982 by Trevor Hughes with other members of the Bristol Exploration Club, then during the early 1990's Vince Simmonds and other, mostly, local diggers were active at a number of locations within the cave, including the start of the dig to the 'east' side of the entrance, leading to An Unexpected Development in August 2018, with Graham Johnson in December 1991. The current phase of exploration was commenced in 2009, with the majority of the early work being carried out by Vince Simmonds and Alex Gee, now the regular team also includes Rob 'Tav' Taviner, Graham 'Jake' Johnson, Nick Hawkes, Jonathon Riley, Paul 'Brockers' Brock, Roz Simmonds, Duncan Price, Mike Moxon and Matt Tuck. There has been occasional help from others including Mike Willett, John 'Tangent' Williams, Pete Bolt, Bob Smith, Callum and Hazel Simmonds, and several appearances by that well-known antipodean, Ray Deasey.

There have been visits from some notable experts in their various fields including: Charlie Self, Andy Farrant, Christopher Smith, Derek Ford, Joyce Lundberg, Don MacFarlane, Marc Luetscher and Gina Moseley. All have added to a better understanding of Hallowe'en Rift.

Just me today. Some spoil management required, the morning spent trying to extricate my boots from especially glutinous mud!

The spoil heap

A low turnout for the first digging session of 2021 but, not wholly unexpected. The UK government has imposed more corona-virus pandemic restrictions, that includes an ever-fluctuating and rather confusing “Tier” system. And, the weather is not great, temperatures are just about at freezing point or below and the roads are icy.

As a follow up to a suggestion that buckets might be much easier to empty, I had made a cradle/skip to pull buckets/containers up and out of the entrance rift and today was an opportunity to try the system out. I had a couple of buckets at home and also, had converted a couple of 20 litre drums into ‘suitable’ containers for spoil. As we were underground anyway, we decided to fill some bags as well. Brockers was upfront filling the bags, I cleared them away and filled the containers, the bags and containers then were shuttled along to the junction. To make it easier to get up and down the ever-deepening pit at the current end of the Soft South a ladder was put in place. It was revealed that the “solid floor” partially exposed last session, is probably a large boulder.

We filled about 30 bags (plus the other receptacles) then decided it was time to move the spoil up to the surface and add it to the spoil-heap. I can categorically state that the 4no. containers were far easier to empty than any of the bags. However, for the alternative to be a success we need a lot more containers when it is considered that we have 100+ bags available to be filled with sediment.

It was also noted that the spoil heap requires some attention, and a redistribution of sediment is necessary.

As I drove back across the border to a “Tier 3 Area” it was snowing quite heavily!
