Rescue crews are searching for US climate journalist Alec Luhn, who vanished while hiking on a glacier in Folgefonna National Park in southwestern Norway.
Luhn, who has worked for multiple news outlets including the BBC, departed for his hike from the town of Odda on 31 July, according to his wife Veronika Silchenko.
He did not show up for his return flight to take him home on Monday, leading her to call authorities.
Rescue operations are continuing, although officials say they are being hampered by poor weather that is preventing helicopters from flying patrols.
Rescue crews are using dogs and drones to conduct the search, the New York Times reported, citing Ingeborg Thorsland, a spokeswoman for the Norwegian Red Cross.
