Balin Miller, a noted mountain and rock climber, fell to his death this week at the El Capitan rock formation in California's Yosemite National Park, his mother said.

The 23-year-old's death was reported on Wednesday, mother Jeanine Girard-Moorman told NBC affiliate KTUU in Anchorage, Alaska, Miller's home state.

“My whole world just fell apart, and it’s tough,” she told the station. “There’s no greater pain than losing your child in such a horrific way.”

Details of how he died are not immediately clear.

Dylan Miller told the Associated Press that his brother was climbing a 2,400-foot route along the El Capitan cliffside alone with the help of a rope when he likely rappelled off the end of his rope.
