Avalanche control

[Phil Waterman]

Hi Hanno

Interesting avalanche control videos.

Made me think of similar operations here in New Hampshire on Mt. Washington in the 1960s. People like to spring ski in Tuckermans Ravine (once went skiing after the 4th of July) but the Ravine has significant avalanche problems every couple of years somebody gets caught most survive. But back to the 1960s they got a whole bunch of dud rockets and for several years there where warning signs with pictures saying if you see one of these don't touch and please report it to the Rangers.
