The 56-year-old last contacted his family at around 8pm on Thursday, September 7, but there has been no contact since then.
A major search operation was launched involving helicopters, dogs, drones and ten different mountain rescue teams, including civilians, RAF and police.
Mr Kelly’s backpack was found on Saturday September 9th and although the search covered a huge area, there has been no sign of him since.

After ten days of “intensive searching”, the Glencoe Mountain Rescue Team (GMR) said it had made “the difficult decision” to limit the search for Mr Kelly.
In a statement, GMR said: “It is still our ultimate goal to return Charlie to his family. GMR and other teams will continue to recruit on a part-time basis when weather permits and volunteers have time between work and family commitments.
“However, if new evidence comes to light that provides a targeted search area, the response may be intensified. To this end, we again ask people to remember September 6th, 7th and 8th.”
Have you been to Glencoe Mountain Resort, Meall a Bhuirdh or the surrounding hills – Creise, Clach Leathad, Beinn Mhic Chasgaig, or perhaps you have seen him in Glen Etive?
“If you were there, please look back at your photos from the day. Was someone in the background of your summit selfie? Also, we would like to hear from anyone who found a pile of orange peels on the hill in this area.” We know Charlie had two on him, but there was no peel in his pocket. This could help us determine his route.
“Charlie is believed to be wearing a black waterproof jacket, gray trousers and a dark green fleece jacket. He was last seen carrying a pair of hiking poles. Charlie is described as having a noticeably unusual gait and possibly moving slowly due to a hip problem.
“Please help us bring Charlie home by sharing with your mountain friends.”
