MAUNA KEA, Hawaii - A man in his 60s had to be rescued after he fractured his femur on Mauna Kea Monday.

Officials say unstable terrain gave way while he was reportedly trying to take a picture.

The man was one mile from the nearest trail at the 12,500 elevation level.

Six personnel carried the patient in a 'skeds.' Due to the lack of oxygen, personnel could only carry him for approximately ten feet at a time before stopping to catch their breath.

Air temperatures were in the 30s, and personnel were rotated as needed.

"Rescuers worked tirelessly despite the cold temperatures and altitude sickness," Hawaii County Fire Department reported.

It took three and a half hours to get the man to safety.
