Weekend avalanches killed five people in Montana, Utah and Idaho, with one bruised survivor traveling miles by snowmobile and on foot to reach help, authorities said.

In Montana's Big Belt Mountains, the bodies of two snowmobilers caught in an avalanche were found by searchers early Sunday and removed by helicopter later in the day.

That avalanche happened Saturday at the base of Mount Baldy, about 20 miles from Townsend. A survivor traveled the 15 or 20 miles back to the trailhead, initially by snowmobile and then on foot after the machine became stuck, Lewis and Clark County Sheriff Cheryl Leidle said.

In Utah, two snowmobilers died in separate avalanches on Saturday.

Earlier Saturday, a snowmobiler on Signal Peak in southwestern Utah triggered the avalanche that killed him, the Sevier County sheriff's office said.

That man, whose name was not released, was climbing the back side of the peak when the avalanche buried him in an estimated 8 feet of snow, authorities said.

In Idaho, the Bonneville County Sheriff's Office in Idaho Falls confirmed the death of a Utah man in an avalanche near Palisade Peak. His name was not immediately available.
