FAIRBANKS, Alaska -- A 9-year-old Alaska boy fell into a deep glacier crevasse and state troopers say he likely did not survive.
The Fairbanks Daily News-Miner reports Sjohn Brown of Fairbanks fell into roughly 200-foot while riding a snowmobile Saturday at the Arctic Man Classic, a race involving snowmobiles and skiers or snowboarders in the Hoodoo Mountains off the Richardson Highway,
Alaska State Troopers say the boy rode around a small mound and disappeared.
Troopers say he apparently fell into a mulan, which forms when water flowing on glaciers erodes ice.
A climber descended into the hole and spotted the boy's helmet and goggles and part of the snowmobile.
Authorities say the boy may be buried in deep snow.
