1. A device for avalanche control, comprising:
a receiver configured to receive a release signal;
a holder configured to hold an explosive charge and coupled to the receiver to release the explosive charge in response to the receiver receiving the release signal; and
a coupler coupled to the holder and configured to attach the holder to an unmanned aerial vehicle to transport the explosive charge to above a snow surface using the unmanned aerial vehicle,
a non-electric fuze assembly coupled to the explosive charge, the fuze assembly comprising a pyrotechnic pull wire ignitor coupled to a fuze, the pyrotechnic pull wire ignitor being connected by a line to the holder, the pull wire ignitor ignites the fuze as the explosive charge falls away from the holder, the ignited fuze being operable for the delayed detonation of the explosive charge to trigger an avalanche.
