The brother of British actor Julian Sands has said he has come to terms with the fact "he has gone".
Mr Sands, 65, disappeared on 13 January while hiking in the Baldy Bowl area of the San Gabriel Mountains, north of Los Angeles.
His brother Nick, who lives in Gargrave, North Yorkshire, said he had already said his "goodbyes".
Californian officials have been unable to locate the actor, saying deadly storms have hampered search efforts.
"I have come to terms with the fact he's gone and for me that's how I've dealt with it," Nick Sands said.
The financial adviser said he preferred that to thinking of his brother lying injured on the mountain side.
But he said clearly his brother's three children and wife were still hopeful he would be found.
"We are all still hoping I guess, but I know he's gone in my mind and because of that I've already said my goodbyes."
Speaking on Tuesday, San Bernardino County Sheriff's Department said: "Numerous ground and air search efforts have taken place.
As of this time, Mr Sands has not been found and no evidence of his current location has been discovered.
