A Snowdonia mountain rescue team is warning walkers to watch out for hidden ice after a fatal fall at the weekend.
The men were walking in sunny but frosty conditions
An inquest has been opened and adjourned on Colin Blundell, 25, from Upton in Cheshire, who died on Sunday following a fall on Glyder Fach.
He fell 100ft from a gully below the main cliff. Although it was sunny at the time, icy patches remained.
Rescue team members were back at the site on Monday, gathering evidence for the inquest.
Ogwen Valley Mountain Rescue Team spokesman Chris Lloyd, said: "At this time of year, ice will be lurking."
Mr Blundell's companion, who is believed to have completed the same scrambling route a week earlier, raised the alarm around 1247 GMT by calling out to other people as he went to help his friend.
Mr Lloyd said a four-strong team went to the area to bring down the companion, while the rescue helicopter from RAF Valley on Anglesey was despatched.
Mr Blundell was airlifted to hospital by the RAF rescue helicopter
After a brief search, the helicopter spotted the man's colleague, then lowered a winchman to where Mr Blundell lay.
A North Wales Police spokeswoman said the man was airlifted to Ysbyty Gwynedd in Bangor, but later died.
Mr Lloyd said the rescue team had no criticism of the two men, who he said were well prepared for the route.
He said that the man's companion had told the rescue team that the two men had stopped for a break after climbing a slanting gully.
Mr Lloyd said the man had described to his rescuers how Mr Blundell 'was standing there one moment and the next he was gone'.
"The rocks are slightly greasy that this time of year. It shouldn't be seen as a criticism - we climb throughout the year irrespective of snow and ice," said Mr Lloyd.
"This was broad daylight, beautiful weather conditions, (but) I suspect there was frost there, icy patches. There are areas where the sun won't have got to, so the ice will be lurking.
"If you slip on that, you are likely to take a tumble."
