Two people were killed in an avalanche near Salt Lake City on Wednesday, FOX News has learned.

The body of a man has been retrieved. The second body has not yet been found.

The slide happened at 10:30 a.m. Wednesday on the backside of Logan Peak in Cache County, Sheriff's Lt. Matt Bilodeau said.

Bilodeau said the two were snowmobiling, and search teams do not believe anyone else was caught in the avalanche.

The area has been considered in "extreme avalanche danger" this week as new snowfall has made the snow pack increasingly fragile.

The Utah Avalanche Center has cautioned people not to venture into the backcountry.
