Authorities on Sunday launched a “body recovery effort” for a man who climbed over a safety barrier at the Grand Canyon Skywalk and plunged more than 500 feet to the canyon floor.

The 28-year-old visitor jumped from the horseshoe-shaped glass walkway — which extends 70 feet out over the canyon — around 4:30 p.m. Saturday.

The walkway, a popular destination for tourists since it opened in 2007, is on the Hualapai reservation just outside Grand Canyon National Park.

The man’s identity has not been released and authorities have not said why they believe he climbed the railing. The walkway is 500 to 800 feet above the canyon floor, overlooking the Colorado River.

He is among several people who have died at the popular national park this year.

Earlier this month, a British tourist was killed while skydiving in tandem with an instructor when the two made a “hard landing” about 15 minutes outside the South Rim of the canyon.

In April, an elderly woman fell to her death when she plummeted 200 feet, just weeks after a 67-year-old man fatally fell 400 feet.

On March 28, a Chinese tourist fell and was killed at Grand Canyon’s West Eagle Point while trying to snap a photo.
