The 19-year-old fell all the way to the river at the bottom of the canyon but escaped almost unscathed at a spot where a handful of people die each year.

The unidentified man, who is reported to be 19, slipped while hiking beneath the High Steel Bridge in Washington State, one of the tallest railroad bridges in the US, on Saturday, the Mason County Sheriff's Office said.
Sheriff's deputies and firefighters mounted a two-hour rescue mission using a rope and harness to scale the bridge and rescue the man who had fallen to the river below, the office said.

West Mason Fire chief Matthew Welander told Seattle-based news outlet, KING 5, an affiliate of NBC News, Sky's US partner, the team "hooked him up into a harness" and brought him all the way back up.

"He was walking down a washout that a lot of people use and has kind of become a trail" and ended up at the river below, he said, adding the man had been "incredibly lucky".
Sheriff's patrol corporal Tim Ripp, who helped rescue him, said: "We've told people to stay off these trails because they're dangerous, but people either haven't seen the warning signs or are disregarding it."

Corporal Ripp said five to seven people fall off the bridge every year, and the majority die, despite warning signs, including one describing how steep, slippery and unsafe the bridge is.
A lack of respect for nature and not paying attention are part of the problem as people continue falling from the bridge, authorities have said.
