An out-of-state hiker has died at the Grand Canyon, National Park officials announced Wednesday.
The incident occurred around 1:20 p.m. on Tuesday below the South Kaibab Trailhead.
Officials say bystanders started CPR on the hiker, identified as 60-year-old William Smith of Oswego, Illinois, but emergency crews were unable to successfully continue resuscitation efforts.
Smith was reportedly hiking out of the canyon after finishing a day hike to Ooh Ahh Point. The death is under investigation, but park officials are urging hikers to postpone difficult hikes. Extreme heat and limited resources have put a strain on rescue crews who have been dispatched to several emergencies this month alone.
