Multiple Hikers Die During Difficult Treks in Grand Canyon National Park

A 36-year-old woman from Indiana died while attempting to hike to the Colorado River and back in a day in Grand Canyon National Park. Park rangers are warning visitors, especially inner canyon hikers and backpackers, to be prepared for excessively hot days in the coming weeks as temperatures on exposed parts of the trail can reach over 120°F (49 °C) in the shade. Hiking in extreme heat can lead to serious health risks including heat exhaustion, heat stroke, hyponatremia, and death. Visitors should evaluate their level of experience and plan accordingly.
