Balin Miller's solo climb and fall was caught on a live stream.

An Alaskan climbing influencer has died after falling from El Capitan, a famous vertical rock formation in California’s Yosemite National Park.

Balin Miller, 23, was live-streamed on TikTok ascending and subsequently falling from the monolith on Wednesday.

In an emotional social media post confirming her son’s death, his mother Jeanine Girard-Moorman said: “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.”

Details of what caused the incident are not clear, but Miller’s brother Dylan told AFP he was lead rope soloing - a technique that enables climbing alone while still protected by a rope - on a 2,400ft (730m) route named Sea of Dreams.
