An Illinois man has died during a hike in Grand Canyon National Park, authorities said Wednesday.
Park officials said 60-year-old William Smith of Oswego was hiking out of the canyon Tuesday after completing a day hike to Ooh Ahh Point about one mile down the South Kaibab Trail when he collapsed.
Bystanders started CPR on Smith and National Park Service emergency medical personnel responded and assisted with resuscitation efforts.
But park officials said all attempts to resuscitate the victim were unsuccessful.
