When you drive through Thompson Pass, you'll see "snow canons" that are used to trigger controlled avalanches in the high country.

The website DroneDJ says DOT is working on a new system –  "explosive-laden" drones that drop mini-bombs onto snow hills. The site said DOT has collaborated with the Alaska Railroad on the project. 

Apparently, there are some regulatory issues with the FAA, as drones carrying explosives are considered "dangerous weapons." 

Avalanches are common throughout Alaska. Just a few days ago, near Cooper Landing in the Kenai, three people were caught in an avalanche and one died. During the 1898 Gold Rush, miners heading over the Valdez and Klutina Glaciers, were caught in avalanches, and killed.
