Officials are reporting three heat-related deaths inside the Grand Canyon, all happening last week. Emergency crews found a 72-year-old man dead Friday along the South Kaibab Trail. In a separate case Tuesday, first responders found a 67-year-old man and 68-year-old woman along the North Kaibab Trail. Officials say temperatures inside the canyon can exceed 109 degrees, even in the shade. The deaths are a stark warning about the danger of hiking in extreme heat.
