I also have been riding Graves Creek for the last ten years. It is an excellent place to hit the steep and deep. A lot more tree riding than Fernie, but it does not take long to be comfortable after riding mostly open alpine (Revy/Golden). Join the local snowmobile club and support their fund...
Just got home an hour ago from Eureka area, 45 miles north of Whitefish. I live near Calgary. There is not much snow this year. Almost none in the valley, snow looks like it starts about 4000' or so. Not enough snow to pull my sleds out of the shop!
