The first solo climb of the enormous granite rock face was completed by Alex Honnold in 2017 as part of the "Free Solo" documentary.
One of the 23-year-old's viewers who saw the incident wrote: "He made it to the summit but he had to retrieve his bags as they got stuck on a rock as he was hoisting them up.
"As he was trying to retrieve the bags he fell to his death, all caught on the livestream.”
Mr Miller's mother, Jeanine Girard-Moorman, paid tribute to her son.
She said: “He’s been climbing since he was a young boy. His heart and soul was truly to just climb.
"He loved to climb and it was never about money and fame.”
An 18-year-old man from Texas was killed in Yosemite National Park earlier this year after attempting a climb without rope on a separate rock face in the park.
A 29-year-old woman suffered a similar tragic fate in August after suffering a blow the head by a large tree branch while hiking through the park.
The 23-year-old's death came on day one of the US Government shutdown, which saw limited operations at national parks across the country and visitor centres shut.
The service team at Yosemite National Park confirmed they have launched an investigation into the tragedy, adding that “park rangers and emergency personnel responded immediately”.
