-15/20ish, it was hard to tell with the wind. but it was some great fluffy colorado powder. just this year i had a -10 day, it really does something to your soul, its like adding and subtracting life all at once.

Sunshine Village for Xmas camp one year. They had to shut the lifts down because the cables were getting brittle. Including the windchill, -55 celcius.
