Roaring Hole was connected by divers to Meregill. Battlefield Chamber in White Scar was opened to tourists. The entrance to Dale Head collapsed. Major extensions were discovered beyond the sump in Gingling Hole. Agreement was reached that 8mm self-cutting anchors would be replaced by resin fixed “P-hangers”. Hymac Hole was opened, the first entrance to be dug with a Hymac digger hired by the “Mendip Mining Company”. A Hymac was used to open the entrance to Whitepit. After 14 years Wigmore Swallet finally went. Major extensions were made in Slaughter Stream Cave. Carno Adit went after nearly 10 years of digging.

David Heap, author of Potholing: Beneath the Northern Pennines, died. James Hall Mine was connected to the Speedwell Cavern streamway. The Main rising in Speedwell Cavern was pushed by divers to –66.5m, already the deepest in Britain but seen to continue and go deeper. Ogof Draenen continued to grow, by February it was the 4th longest cave in Britain. Dry weather again led to an airspace through Swildon’s Sump 1 and bad air problems in the cave. Divers discovered Uamh an Claonaite 7 where huge extensions restored the cave as the longest in Scotland. A shaft in Brezno pod velbom was claimed to be the deepest underground shaft in the world at –501m, there is a ledge of sorts at –377m but the rest of the hang is free.

1998 The deaths occurred of Mike Dewdney-Yorke and PB Smith, both larger than life cavers. The Ogof Draenen land sale was still not finalised although the cave continued to grow. Pollution problems causing bad air led to the closure of Otter Hole.
