The European Space Agency, almost certainly in close league with the Fédération Internationale de Ski, reports that there is indeed year around skiing on Mars. The 80-plus kilometer-wide crater appears to offer both nordic and alpine skiing opportunities. For area photos, please see this linked NPR article.
The take-home for Helena-area skiers is obvious: During low-snow years, or during years of excessive-hyphenation, we have the option of packing up our skis and hitching a ride on one of the increasingly-frequent (if highly irregular) Mars exploratory flights, and make tracks in a remarkably untracked venue.
Happy holidays, and see you on the (Korolev) slopes.
