The death of a hiker in Grand Canyon is just the latest incident in what has been a deadly summer in America's National Parks.
Authorities found the body of the Grand Canyon hiker, who was reportedly unprepared for the conditions, on Sunday.
Two backpackers ran across the man on Tanner Trail close to the Colorado River on Friday. They noted that he looked exhausted and was hiking without a pack.
According to a press release from the Park Service, the couple met the man, gave him water, and advised him to join them. The solo hiker declined and headed off in the direction of the river. The couple later passed the man's abandoned pack and returned on Saturday, carrying an extra gallon of water for him.
In the latter half of last week, temperatures in the Grand Canyon reached upwards of 108 degrees Fahrenheit with much of the Tanner Trail wide-open and exposed to the elements.

As soon as the couple returned to the South Rim on Sunday, they reported the man to Park Service personnel. Noticing that the man's car was still in a parking lot, rangers flew over the canyon in an attempt to spot him.
The man's body was located around 10:45 a.m. Sunday in a wash just above Tanner Beach.
His identity is being withheld pending notification of his family, and the National park Service is investigating the death.
The incident comes just hours after a man was found dead in Yellowstone National Park on Friday along the Mary Mountain Trail.
