The risk is part of the excitement of big-wave surfing — but it can be too much.
Sion Milosky, 35, died on Wednesday after after a large wave crashed down on him at California’s Mavericks Beach.
Said Chris Killen, a filmmaker who taped Milosky's final wave:
"He was really deep and he makes the drop, and the end section comes and just explodes behind him as he straightens out. I'm looking over just devastated. His head's flopping, and I could tell he was blue from far away."
Waves at Mavericks can reach 80 feet in height — witnesses say that the one that killed Sion was at least 50 feet.
