Beacons help locate Idaho avy victims
April 14, 2009
KETCHUM, Idaho ” Yet more evidence arrives that all the tools in the world might not save you if caught in an avalanche. Snowmobilers both in Idaho and British Columbia died in recent weeks, and the stories were remarkably similar.
In the Idaho case, a 38-year snowmobiler was high-marking in the mountains north of Sun Valley, seeing how far up a steep slope he could go before being forced by gravity to turn around. The avalanche left him buried under 7 to 10 feet of snow.
Three of his companions observed the avalanche, and were able to pick up the signal from his beacon within minutes. All were equipped with snow shovels and probe poles. They also had a satellite phone, and one of them was an emergency medical technician.
Still, because of how compacted the snow became in the avalanche, it took them at least 20 minutes to reach the victim. The county coroner said the man died of asphyxiation. He leaves behind two children and a wife.
In Canada, along the Continental Divide in the Monashee Range, a 24-year-old snowmobiler had reached nearly the apex of a steep-faced, above-timberline slope when he triggered an avalanche. He had been among 10 snowmobilers who had spent several hours high-marking on the slope.
The Edmonton Journal says that despite avalanche beacons and probes, it took his companions 30 minutes to locate and excavate the victim from under more than 6 feet of snow.
