Park officials said in a statement Monday that 26-year-old Robert Durbin of Corvallis, Montana, died Saturday.
They say Durbin was taking photos along Haystack Creek next to the Going-to-the-Sun Road, which is known for its dramatic scenery and vertigo-inducing heights.
He fell into the creek and was washed through a culvert that goes beneath the road and empties into a 100-foot drop down a cliff.
