Hiker Found Dead at Grand Canyon National Park

GRAND CANYON NATIONAL PARK, Ariz. -- A hiker's body has been found on the southern rim of the Grand Canyon National Park in Arizona, two days after he was seen in an exhausted state, park authorities said Monday.

Two hikers last saw the man on the Tanner Trail Friday and noticed he was visibly distressed by the extreme heat, which park authorities said reached high temperatures of between 103 and 108 degrees from Wednesday to Sunday.

According to a statement issued by park authorities Monday, the man did not take his fellow hikers' advice to go with them to a nearby river. The following day they found the man's abandoned backpack, prompting them to notify authorities when they returned to a nearby campground on Sunday.

A park helicopter was called in and spotted the man's body on Sunday. The National Park Service is investigating the incident.
