With a month off don't plan any specific spot western Canada/US.
Look at who is going to get hit with the best storm and chase it.
My most memorable trip started in Calgary, took me to Kicking Horse, Fernie, Squaw Valley, Kirkwood, Alta, Jackson Hole, Nelson, and some cat skiing back near Fernie.
Two weeks of storm chasing bliss.
Pack a sleeping bag and split nights between sleeping in the car and hostels.
Thanks for all the tips everyone. Yeah I think since it will still be early season (planning on going early-mid January) I will probably just wait and see which mountains have the most snow. My only worry is that I have an avg 2 wheel drive car with winter tires so don't want to venture too far where the driving can be sketchy…
