I've taken 2 elk with a bow hunting with Glenn Smith - 5S Ranch Outfitters - out of Trout Creek, MT. This was in the late 80's and he may have retired and his son Jeff started Bullseye Outfitters with a friend of his from Michigan, not sure if they're still in business or not. A DIY hunt might be difficult if you're not familiar with the area. And there's only 2 directions in that section of Montana - straight up and straight down!
The morning I shot my first elk in '87, we watched a bull shred a tree about 100 yards up the side hill. I heard some coyotes howl and the bull moved off. I asked Jeff if those coyotes scared the bull off and he said those weren't coyotes howling they were wolves!
We cut up my elk and moved it into the shade and then hiked backed down to the truck as we were going to go back to get the horse to pack it out. We had parked at the start of a slag road that was blocked off for vehicle travel. When I got into the truck there was a sign that I didn't notice in the dark morning that read "Caution - Grizzly Bear Habitat". Now that perked up the old butt cheeks?
Good luck.
