Avalanches, masses of snow moving down a slope, happen most often in the wilderness. The National Avalanche Center says watching for forecasts, bringing the proper gear and getting training to prepare for them can help with outings. The center says each winter in the United States, about 25 people die in avalanches. They form on slopes steeper than 30 degrees when layered snow breaks and slides. Experts say wind, rain, heavy snow, or movement can add the final pressure. Victims or their partners trigger about 90% of fatal or injuring slides. Skiers, snowmobilers and snowshoers can check forecasts, travel with a buddy, and carry a beacon, shovel, and probe.
