The man was with a female companion when he went through a wind-blown cornice near the summit of 4012ft-high Carn Mor Dearg.
The Lochaber Mountain Rescue Team, police and a Stornoway Coastguard search and rescue helicopter were all alerted just before noon yesterday.
John Stevenson, leader of Lochaber Mountain Rescue Team, said the man was lucky to have escaped injury.
"He had a lucky escape. The snow saved him."
