Absarokee / Beartooth Mountains
1 death
What happened
A group of seven snowmobilers was riding north of Cooke City when an 18 year old from Minnesota was caught in an avalanche on a steep, northwest facing slope on Crown Butte outside Cooke City. The victim was stopped on the slope while two others were riding on it when the avalanche was triggered. The others rode off, but the victim was caught and buried. Neither he, nor anyone in his party of seven, was wearing a beacon. He was fully buried and Cooke City Search and Rescue located him with a probe pole under six feet of debris near the toe of the avalanche about 1.5-2 hours later. |The avalanche broke 700 feet wide and 2-5 feet deep on depth hoar crystals about 1 foot above the ground. The avalanche ran 800 feet vertical and 1600 feet slope distance. Debris ranged from 5 to 15 feet deep and covered an area 900 by 400 feet. Slope angles in the starting zone ranged from 36 to 38 degrees. For a more detailed report, please see the avalanche incidents report at http://www.mtavalanche.com.

1 death
What happened
A snowmobiler died in an avalanche on Saturday, December 19th outside Cooke City. The avalanche occurred on the southeast face of Sheep Mountain between Lulu Pass and Round Lake. The slide was triggered from low on the slope by the victim who was subsequently buried six fee deep. The victim had an airbag but was unable to deploy it. The slide also caught two other party members who were parked in the run out zone. One was buried up to his chest while the other was completely buried. They both deployed their air bags and escaped without injury. For a more detailed report, please see the avalanche incidents report at http://www.mtavalanche.com.
