A man's body was discovered about a quarter-mile from the summit of Mount Humphreys on Saturday in extremely cold and windy conditions.

According to information from the Coconino County Sheriff's Office, hikers found 53-year-old John Greer of Goodyear unconscious and not breathing at about 11:30 a.m. Sheriff's officials say the hikers gave Greer CPR for about 30 minutes, but were ultimately unsuccessful.

A group of Search and Rescue personnel from the sheriff's office, outfitted in cold-weather gear retrieved the body. The body then was transported by helicopter. The cause of death has not yet been determined and an autopsy is underway.

"We don't think it was foul play," said Coconino County Sheriff's Office spokesperson Gerry Blair. "We were experiencing low temperatures and high winds at the time."

The Arizona Department of Public Safety helicopter couldn't land in the area, so the body was suspended beneath the aircraft with a rope.

A remote weather station on Agassiz Peak recorded temperatures at around 22 degrees at the time and winds on Saturday ranged from 30 to 45 mph, according to the National Weather Service in Bellemont.

The man's family said he was an avid runner and hiker and doing high-elevation training in Flagstaff for an upcoming race.

A running race results website lists Greer as having competed in the Whiskey Row Marathon in Prescott earlier this month.
