GRAND CANYON NATIONAL PARK, Arizona — Authorities at Grand Canyon National Park say a 36-year-old man from Japan has died during a hike on a hot day.
Park officials didn't immediately release the name of the man Friday.
It's the fifth reported fatality at the Grand Canyon this year.
A hiking party called rangers for help near the Devil's Corkscrew on Thursday afternoon.
When rangers arrived, hiking party members say they had tried to resuscitate the man but he didn't have a pulse for about two hours.
They say the man was on his way back up the Bright Angel Trail after hiking down to the Colorado River.
Park officials say the temperature on the trail Thursday was in excess of 110 degrees and the National Weather Service had issued an excessive heat warning.
