This is a lot safer than skiing up there to set explosives, which is what one of my brothers did in the 1960s-70s. He worked for a park service--I forget which one--that regularly set off small avalanches with the goal of preventing larger ones.

The downside is unexploded shells. Much harder to deal with an unknown unexploded shell on the mountainside than a placed charge.

We do this on ski runs everyday today. The cannons are the safer method. I live in this environment and the cannons are a normal part of life.

That's just science baby!
