Ok, its warmed up here to a balmy -17 C to -18 C (about 0 F) at 81%
relative humidity, and yes the snow still squeeks.  Not as loud, and
more of a rusty hinge type of squeek, but still definite squeeking.  One
more observation, if you step down with your heel and twist, you get a
faint very high pitched squeek.
