Roundtop made snow???

Well i decided to check out roundtop's cam yesterday for some absurd reason (never thought i would see any white on the ground) but low and behold they have made snow! I am guessing it was just a test but the guns must have been on for a while if all that snow survived yesterday's very warm rain. Anyone know when they turned on the guns and what their plans are for opening (aka anyone have an inside source)?

live pic from the cam:

They made snow on saturday night for their rail jam coming up. I dont think they made snow with intentions of opening, just for their rail jam.
