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 present dig 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 includes Rob 'Tav' Taviner, Graham 'Jake' Johnson, Nick Hawkes, Matt Tuck, Jonathon Riley, Paul 'Brockers' Brock, Roz Simmonds, Duncan Price and Mike Moxon. There has been occasional help from others including Mike Willett, John 'Tangent' Williams, Pete Bolt, Bob Smith, Callum and Hazel Simmonds, with regular guest appearances by that well-known antipodean, Ray Deasy.

With Jake and Tav

I wanted to look at the current dig to see whether an application of IRS might be required and to photograph the fractured stal in the north/south rift at the [current] furthest point of the passage, perhaps evidence for earth movements. Jake is off to Scotland for a month, also wanted to get a good look at the current dig. Tav thought it a good time to get some surveying done. We did all those things. About 40m of passage surveyed. A good evening and the prospects ahead look very encouraging.

The way forward is obstructed by some slabs of degrading flowstone, they are loose but there’s not quite enough space to shift them. The floor can be dug-out to give more room for progress to be made. About 4m ahead there appears to be more space and there is cool air movement.
