"The person caught in it was recovered deceased," spokeswoman Megan Peters told CBS affiliate KTVA in an email.
Troopers and National Park Service officials responded to reports of an avalanche some 90 miles north of the state’s largest city Anchorage on Saturday afternoon.
The Alaska Dispatch News outlet relayed witness accounts of snowmachiners in Hatcher Pass attempting to rescue the victim, a young man, buried in snow for over an hour.
An emergency services deputy director, Lisa Behrens, said snowmachiners at the scene were conducting CPR when rescue crews arrived.
"Every possible effort was made to resuscitate the patient," Behrens told the newspaper.
Hatcher Pass was the site of a January 3 death of a snowmachiner in what was described as a "freak" avalanche, and a November 22 death of a skier.
