Third person dead after Ben Nevis avalanche
A huge rescue operation was mounted involving Lochaber and Glencoe mountain rescue teams, Coastguard helicopter crews, military personnel, police and the ambulance service.
Paul Boggis, a mountaineering instructor, was among climbers in the area who helped to carry the climbers from the scene of the accident.
He said one of his clients had heard what they thought were shouts for help. Soon after, people could be seen heading for an area below Number 5 Gully, and then a Coastguard helicopter appeared close by. Mountain rescue teams, the coastguard, police and ambulance service were involved in the rescue effort Mr Boggis did not go with his clients to the slope beneath the gully for fear of further avalanches, and instead went for where a group of people had gathered around a casualty below the slope.
He told BBC Scotland: "We asked if we could help and we were asked if we could help with that casualty.
"The others had transceivers (emergency locator beacons), we didn’t have transceivers, and they headed for the snow slope in the firing line of Number 5 Gully.
"So there were some very brave people on the scene who were helping the casualties."
Mr Boggis did his best to make the casualty he was with comfortable, before he and his two clients helped to carry him from the scene.
