Seamus Lawless, a Trinity College professor from Bray in Co Wicklow, fell while in an area near the summit known as the balcony yesterday.
The GPS worn by Mr Lawless was found almost 500 metres from where he fell, however experts say it is possible that the device became detached from Mr Lawless. Winds of up to 100kph are being experienced on Everest and the temperature is dropping as low as -45C.Mr Mingma confirmed he has spoken to Mr Lawless's wife.
"We are very sad because we have lost one of our best mountaineers. Everybody is very upset in the Himalayas."A mountaineer who has twice reached the summit of Mount Everest has said his thoughts are with Mr Lawless's family and friends.
