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 Caroline Allen, 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.

With Tav and Tangent, Alex came along later to assist with the haul out.

Cleared the debris from Wednesday evenings little passage widening exercise and managed to fill quite a few bags of sediment as well. Nice and tidy ready for a little more attention on Wednesday next.

Solo underground but Tangent was on the surface exploring the surrounding landscape, it was a rather fine evening!

Underground I dragged the kit along to the rift north at the bottom of the pot where the new drill (Erbauer 36v)was unpacked ready to be used for the first time. Kept drilling until batteries were fully discharged but only charged 5no. As usual there was high variability in the conglomerate and the calcite. Job done it was time to return to the surface and a satisfying pop was heard, cave locked, and off we went.
