FLAGSTAFF, Ariz. -- A Union City man rescued early Friday from the bottom of a mine shaft in northern Arizona's Meteor Crater reportedly jumped in to "appease the gods," authorities said.

Coconino County Sheriff's officials said Parminder Singh told deputies after the eight-hour rescue in freezing temperatures that he intentionally jumped into the shaft, which is 100 feet deep and closed to the public.

Singh, 28, was reported to be in stable condition at Flagstaff Medical Center.

Hospital officials didn't immediately return calls Friday about Singh's injuries or a condition update. Calls to Singh's hospital room went unanswered.

Meteor Crater, a tourist attraction 35 miles east of Flagstaff, was created by an asteroid about 50,000 years ago. It is nearly 1 mile across, 2.4 miles in circumference and about 600 feet deep.

An employee at the park called the sheriff's office about 4 p.m. Thursday to report a man trespassing at the bottom of the crater.

He then told authorities that he watched through binoculars as the man jumped feet first into the mine shaft, which is surrounded by a 7-foot-high fence topped with barbed wire.

It took hours for rescuers to get to the opening of the mine shaft and they were battling 20-degree temperatures with a wind chill factor of below zero.

They called out to Singh about 8:20 p.m. and got a faint reply, indicating he was still alive.

Sheriff's officials said rescuers lowered food, water, warm clothing, a flashlight and a portable radio to Singh so they could communicate with him.

A member of the Flagstaff Fire Department's technical rescue team was lowered into the shaft to provide initial treatment to Singh, who they said had severe hypothermia.

Singh was carried up the 600-foot crater incline and then more than a mile to the visitor center's parking lot before he was transported to a hospital.

More than 30 responders from various agencies around Arizona assisted in the rescue, authorities said.
