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, their interest waned by the late 80s. 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 with Graham Johnson in December 1991. This led to the discovery of An Unexpected Development in August 2018. 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, in 2023, the core team comprises: Vince Simmonds, Rob 'Tav' Taviner, Graham 'Jake' Johnson, Nick Hawkes, Jonathon Riley, and Paul 'Brockers' Brock. There is/has been help from others including Mike Moxon, Roz Simmonds, Duncan Price, Phil Coles, Caroline Allen, Mike Willett, Matt Tuck, 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.
