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 Jonathon, Jake, Nick and Brockers.

Festivities over, things return to normality.

My turn up front, digging; Jonathon, after three days on his sick-bed had wrested himself away to attend, stood in the 'drippiest' spot and cleared away the filled bags to Brockers, back on the slippery slope. Brockers, in between bags, ventured down into Tuck Shop to break-up some of the rocks still there. Jake was on top of the slope and Nick on the haul and shuttle, the spoil stashed in the entrance. Nick, also, dug a channel to drain away the puddles along the passage from the entrance.

Some bailing of water was required before the digging effort could commence, this didn't take too long. Continued to follow the choked rift, as forward progress was made, the sediment remaining overhead became self-digging, largely induced by a strong seepage of water. A bar was utilised to alleviate this occurrence, revealing a narrowing of the rift above, lower down the rift continues, there is a small gap over the top where air movement can be detected, and it's wide enough to work.

The usual 50 bags took a bit longer to fill than anticipated and the call came that the team were leaving to start emptying the bags, Jonathon and I filled the last couple of bags and joined them. All of us were suitably coated in mud after today's effort.
