Mountain climber Marty Schmidt.
New Zealand mountain climber Marty Schmidt and his son, Denali, are missing on the world's second highest mountain, K2, following an avalanche.
The father and son have not been heard from for two days and a report from a British mountaineer has confirmed the New Zealand Alpine Club's worst fears.
General manager Sam Newton said: "They believe that Marty (53) and his son Denali (25), were killed by an avalanche at Camp 3 (7,400m) on July 26th or 27th"
"More details will emerge in the coming days and tributes to Marty's extraordinary character and achievements will follow. Right now, our thoughts are with the friends and family who have suffered a tremendous loss," Mr Newton said in a statement.
