A caver’s body has been brought to the surface after lying underground for more than 39 years.

Paul Heinz Esser died in February 1971 while cave diving in Porth yr ogof in the south of the Brecon Beacons national park. The remains of the trainee diver were recovered last week by two members of the South & Mid Wales Cave Rescue Team.

Mr Esser was a 21-year-old medical student at Bristol University at the time of his death in a sump on 13 February 1971.

Family members were present at the site, near Ystradfellte, when his body was brought above ground on Thursday. Several attempts had been made in the past to find and recover his body.

Investigators concluded Mr Esser, who had progressed from open water diving to cave diving, had followed a fixed line that had become detached and washed downstream, erroneously thinking it would lead him along a safe route.

Porth yr ogof has the reputation of the second most deadly cave in modern British potholing, having claimed 11 lives since 1957 including Kevin Sharman, a 17-year-old trainee soldier, the last to perish in the system in July 2002.

He died at the Resurgence Pool, the site of which has seen 10 of the deaths.

Only the Three Counties system on Leck Fell on the western edge of the Yorkshire Dales national park has claimed more lives – 12 – and includes Lancaster Pot, Pipikin, the Easegill system and Lost John’s Cave.
