I work snowmaking at Hockley Valley resort in Ontario. Its an awesome job if you love snowmaking in general and can handle the cold.
Snowmaking isn't for the regulaur kinda person.. it can be a dangerous job depending on the guns your using, especially when you start to deal with fan guns with crappy nuke lines and your blowtorching stuff all night..
If your shift is starting up you would usually hook up the guns, start up the pumps, fix any guns that are frozen up or arn't pumping right and adjust them for the wind and temperatures..
At our resort if you get a midnight - > 8 am shift you usually get to move alot of guns for daytime positions off the trails and to the sides, this starts around 2'ish depending on the hill and where grooming is at the time.
and if you ever get stuck with a gun thats frozen and the waterline is full of pressure, pull, pray, run. When its full of pressure you have to try to release a hose filled with up to 300 pounds of pressure, thoe things can fly when both latches come off...
Other than that, fucking enjoy it.. its a pretty chillin job when your working with cool staff especially at smaller resorts.
