In a tragic accident, a tourist from Hong Kong went over the edge at the Grand Canyon in Arionza as he was trying to take a selfie. He died after falling from a 1,000-foot ledge. It was near the rail-protected Sky Walk, but not on it.
Last fall at Yosemite National Park, a travel-blogging couple fell 800 feet to their deaths from a cliff as they were attempting to take a selfie.
According to a study, 259 people have died while taking selfies during the period from 2011-2017. Of those, over 70 percent were men.
In the case of the Grand Canyon, it is impossible to install safety rails along the over 277 miles of rugged ledges and canyon terrain.
