BOZEMAN, Mont. -

The Gallatin National Forest Avalanche Center says Wednesday night's avalanche buried a man under five feet of snow.

Search and Rescue crews learned of the slide late Wednesday evening.  A party of three snowmobilers entered the northern Gallatin Range in the Portal Creek area between Bozeman and Big Sky.  According to the avalanche center the party was near the bottom of the slope when the avalanche hit.

One person was partially buried, a man in his 40's was completely buried.  Members of his party found him using a beacon and attempted CPR for 40 minutes but were unable to revive him.

46 year old Burton Kenneth Gibson was buried and killed in the slide.  One member was able to dig himself out.  The two other riders located Gibson using avalanche transceivers, uncovered him and attempted CPR. Search and Rescue crews planned to fly in by helicopter early Thursday and recover the body.

On Wednesday, the Gallatin National Forest Avalanche Center rated the danger in the Northern Gallatin Range at high on all slopes.  Avalanche danger Thursday is listed between considerable and high depending on terrain.
