a major concern of ski resorts is avalanche control. there are two ways to prevent avalanches blasting the snow with explosives or erecting snow fences . explosives are primary used to prevent avalanches, especially at ski resorts. the effect of the explosion loosens the top layer of snow , which tumbles harmlessly down the mountainside. and snow fences prevent the buildup of snow on the downwind side of ski runs.for your safety,you can carry beacons of gps devices . however , it is very unlikely someone will survive an avalanche.
