A 23-year-old climbing influencer died during a livestream of him scaling El Capitan, a famous vertical rock formation in Yosemite National Park.

Balin Miller fell during his ascent on Wednesday, his mother Jeanine Girard-Moorman confirmed to the Associated Press.

'He's been climbing since he was a young boy,' she said. 'His heart and soul was truly to just climb. He loved to climb and it was never about money and fame.'

On Facebook, the mom added: 'It is with a heavy heart I have to tell you my incredible son Balin Miller died during a climbing accident today.

'My heart is shattered in a million pieces. I don't know how I will get through this. I love him so much. I want to wake up from this horrible nightmare.'
