Greg - sounds like you have a pretty firm grasp on what to expect. Montrose is only 6,000 feet in elevation - but I'm assuming you will be hunting somewhere uphill of the actual town . There are lots of elk at 8,000 feet in that area, but in September the big bulls are often in the big basins up near timber line - like 11,500 feet. I would also suggest you get a multitude of cow elk calls and practice extensively. Some of the best sounding calls are either diaphrams or the ones you bite down on. There are some good CD's out there . . . .
