A British climber who was crushed to death by falling rocks at Yosemite National Park has been named.
Andrew Foster, 32, from Wales, was trapped when more than 1,000 tonnes of rock fell from the face of the El Capitan monolith on Wednesday.
A spokesman for the park confirmed Mr Foster's identity, while his wife Lucy Foster - who was also hiking - was injured and remains in hospital.
Mr Foster was killed attempting to save his wife, Lucy, who was injured and remains in hospital.
Mrs Foster spoke to her husband's aunt and said she was only alive because Andrew jumped to save her.
Gillian Stephens told the Times: "She said: 'Andrew saved my life. He dived on top of me as soon as he could see what was going to happen. He saved my life'."
The couple were keen adventurers and kept a blog documenting their travels. Reports say they were celebrating their first wedding anniversary with a three-week trip to the national park.
The couple, found with climbing equipment, are believed to have been scouting out the ascent from a trail when a "sheet" of granite around 40 metres by 20 metres plummeted from a height of 200 metres.
A statement on the park's website says the couple "were in the park to rock climb but were not climbing at the time of the initial rockfall".
Speaking on Thursday, Scott Gediman, from the park, said: "With all the craziness I don't exactly know where they were going but chances are they were going up.
"From what I understand they were buried under rock... They were crushed by falling rocks."
He could not be specific about their injuries but said they were "consistent with tonnes of granite falling on you".
They are the only known casualties despite being with a group of other climbers when the series of collapses struck, but a search is ongoing.
One witness, Mike Kane, tweeted that the collapse was "very loud", adding it was a "miracle more (were) not hurt".
Meanwhile, a second rock fall at the site on Thursday left one person injured who was airlifted to hospital.
Mr Foster's death is the first fatality from a rock fall in the park in four years when another climber was killed, according to the parks service.
Prior to that, the last climber to die from a similar accident was in 1999.
A Foreign Office spokesman said: "We are in contact with the local authorities and providing assistance to both families at this very difficult time."
