I played the Yellowstone Club yesterday in southwest Montana. It's a mountainous Weiskopf design at like 7,000 feet elevation -- ball rolls out about 200 yards in some cases. I loved the spit-fairwayed, driveable-par-4 17th hole.
Saw a moose on the course, a bear afterward. Carts come with bear spray. Find out more about Yellowstone Club in the Course Finder
