Hiker Dies In Grand Canyon In Triple-Digit Heat

A 57-year-old woman died on an 8-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 an 8-mile 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.

A large part of the Southwest, including the Grand Canyon area, was under an excessive heat warning Monday. The temperature in Phantom Ranch was 114 degrees, the National Weather Service said.
