They say the 28-year-old visitor to the tourist spot on the Hualapai reservation outside Grand Canyon National Park jumped around 4:30 p.m. Saturday.
A Grand Canyon West spokesman says a body recovery effort began Sunday morning.
Skywalk opened in 2007. It’s a horseshoe-shaped glass walkway that juts about 70 feet over the canyon overlooking the Colorado River.
The vertical drop from the Skywalk is between 500 feet and 800 feet (244 meters).
A Chinese tourist fell to his death in March when he stumbled while trying to take a photo close to Skywalk.
