Cat Skiing in Montana
The bar for advance reserving cat skiing is much higher than for resort skiing. This operation likely has similar altitude (no more than 7,000 feet and minimal above tree line) and snowfall (~300 inches) to Big Red across the border in Canada. Terrain may be great but preservation of powder snow since the last dump may not be.
If you're in the area and know recent weather has been cooperative, go for it.
I'm sure sibhusky knows that post-January the number of days cat skiing would have been worthwhile in her region were few and far between.
We all know 2014-15 was not a good year, but my advice stands to avoid committing serious $$$ far in advance to cat skiing in that climate zone.
And I will also note that Liz and I had a very nice powder day Feb. 28, 2013 at Wild Horse Snowcat across the border. We reserved that the day before at the standby rate of $275. Just in time, as it rained at nearby Red Mt. the next day.
+1 In 2014 a couple of acquaintances flew into GEG for a 4-day weekend, and skied powder for the first 3 days at Lost Trail and Discovery in western Montana because they left their options open to the last minute. Meanwhile I was at the end of my annual Canadian trip, under subzero Arctic high pressure across the border. We met up on the last day for all of us at Lookout Pass for more powder on the way back to Spokane.
