Alaska State Troopers spokeswoman Megan Peters says the body of Shjon Brown, of Fairbanks, was recovered at 12:40 a.m. Monday.
The boy was on a snowmobile outing Saturday with his father and others in the Hoodoo Mountains. His father told troopers Shjon drove around a small mound and did not reappear.
Officials say the boy fell an estimated 200 feet into the crevasse through a moulin, a hole formed when water on the glacier surface erodes ice below.
Climbers who descended into the hole say they found Shjon's body buried in six to eight feet now snow underneath his snowmobile.
The Hoodoo mountains are south of Delta Junction off the Richardson Highway.
