Detailed explanation-1: -Avalanche control and mitigation Avalanche mitigation teams use different kinds of tools to do their work. For example, they may remotely trigger avalanches by using an explosive air blast. Teams may also use hand-thrown explosives on the slopes.
Detailed explanation-2: -When an avalanche hazard develops, we use artillery or explosives to trigger the avalanche. These are various methods of delivery, depending on the topography and accessibility to the avalanche path. Explosives are placed by hand, cable-pulley bomb trams, or with surplus military weapons.
Detailed explanation-3: -“Being in an avalanche is like being caught in a fast-flowing river. The most common advice is to move diagonal to the avalanche or try to make your way to the edge, where the slide is not moving as fast and where you’re not likely to be buried as deep.”
Detailed explanation-4: -Once the resort opens, patrollers actively manage the snowpack. That means checking terrain and trying – in two main ways – to trigger avalanches. For steeper, more avalanche-prone terrain, patrollers use explosives. At Schweitzer, patrollers use charges of dynamite that weigh 2.2 pounds.
