GRAND CANYON NATIONAL PARK – There have been 13 helicopter rescues in just seven days at Grand Canyon National Park with emergencies including heat illness, dehydration, and even hyponatremia, which results in low sodium levels from overhydration.
“With more heat on the way and triple digit temperatures forecasted for this weekend, hikers and backpackers — especially those attempting rim-to-rim or other strenuous routes — should be self-reliant,” said the National Park Service.

If you’re visiting the Arizona national park, make sure you avoid hiking in the inner canyon between 10 a.m. and 4 p.m. because it can be dangerously hot. Carry plenty of food and water, and be aware that help may be delayed due to limited staffing and high call volume.
