All of these Montana closing dates are subject to change at each ski resort's discretion, depending on end of season snow conditions and other factors. Several Montana areas have flexibility in their closing dates.
Warm, windy and not covered in snow...not exactly what you think of when I say "Montana in the Winter". Winds up to 70 mph are possible on Saturday for Bozeman, Manhattan, Boulder and Townsend.
Dangerous, gusty winds up to 60 mph will continue until mid-day Tuesday through Livingston and the I-90 corridor. Ground blizzard conditions may exist.
