Four climbers who died in an avalanche fell around 1,000 feet and ended up buried under up to two metres of snow, the man who led their rescue attempt has said.
Andy Nelson, deputy head of Glencoe Mountain Rescue, said being caught in an avalanche was "a brutal experience".
The two men and two women were found dead on Saturday after the accident on Bidean Nam Bian, a mountain near Glencoe in Scottish Highlands.
They were among a party of six. One man escaped using his ice axe but a 24-year-old woman from the Durham area is in a critical condition.
Mr Nelson, who co-ordinated the rescue, said: "Being in an avalanche is literally like standing on a carpet and having it pulled out from underneath you. Any thoughts of trying to swim out from it is futile.
