Salt Lake City ? A man died after being caught in an avalanche Saturday while snowmobiling near Tower Mountain in the Wasatch-Cache National Forest, authorities said.

The man was with at least three people but was the only one caught in the slide, according to the Wasatch County Sheriff’s Office.

His friends dug through the snow looking for him, first finding his snowmobile and then his body. They administered CPR and called for help, police said.

The man was flown to the University of Utah Hospital, where he later died, police said.

Authorities have not released his identity.

The Utah Avalanche Center had listed the avalanche danger for Saturday as “considerable,” according to its Web site. “Considerable means human triggered slides are probable and natural avalanches possible,” the forecast states.
