A 57-year-old woman died on an eight-mile hike in Grand Canyon National Park on Sunday, when temperatures topped 100 degrees, park officials said.
Park rangers got a call about a hiker in distress at 6:30 p.m., and when the woman was found in a remote area of the park at 1 a.m. she was dead, the National Park Service said in a statement.
She was on a hike in the Tuweep area of Arizona, which is described as a remote region.
The heat was well over 100 degrees Sunday. A cause of death is under investigation, but the park warned of the dangers of extreme heat in a statement Monday.
