On April 14, 2010 a snowmobiler died in an avalanche in McAtee Basin near Buck Ridge just south of Big Sky. He was parked near the base of a north facing slope filming another rider climbing above him. As this rider reached the top of the slope, it fractured well over 1000 feet wide and 2-4 feet deep on a thin layer of weak facets. The victim was carried 200 feet downhill and buried. His partners initiated an immediate rescue and found him very quicly. Digging him out of the debris was difficult because his sled was on top of him and there were many tree limbs in the way. Even with these difficulties, his partners dug him out in less than 15 minutes but it was too late. Our sympathies and condolences go out to his family and friends. A few photos and videos are posted, and the full report will be posted in several days.

Bozeman man dies in avalanche

Posted: Thursday, April 15, 2010 2:00 pm

BOZEMAN — Gallatin County officials say a 57-year-old Bozeman man has died after being caught in an avalanche while snowmobiling in Madison County.

Sheriff Jim Cashell said Stephen Green was caught in a snow slide at about 1:15 p.m. Wednesday in the McAtee Basin area southeast of Ennis. Friends using avalanche beacons found him under 6 to 7 feet of snow, but Cashell said emergency personnel were unable to revive Green.

Family friends said Green — an avid and experienced snowmobiler — was off his snowmobile filming other riders above him when the avalanche broke free.

“They cut him out fairly quickly,” said Mark Staples with the Gallatin National Forest Avalanche Center. “They gave him the best shot they could. Unfortunately, it wasn’t quite fast enough.”

Green’s wife, Carol, said Thursday that her husband “died doing what he loved.” Together, the couple raised two boys, ages 20 and 24.
