William Currie, 18, from Penzance, Cornwall, died after the avalanche in the Cairngorms on Thursday.
RAF Squadron leader Rimon Than, 33, who was based at RAF Valley, North Wales, and Flight Lieutenant Fran Capps, 32, originally from Dulverton, Somerset, also died.
The avalanche struck as two groups of six climbers made their way up opposite sides of a gorge.
One group was part of a Glenmore Lodge-organised winter skills training course and the second was off-duty RAF personnel.
The three were airlifted from the Chalamain Gap area to Aberdeen Royal Infirmary but died of their injuries.
Police, Cairngorm mountain rescue team, Cairngorm mountain ski patrol, search and rescue dogs, RAF Lossiemouth's rescue team and three helicopters were involved in the rescue operation.
