This my unit, hunted it many years now. It can be many different things, hot, dry, wet flooded just never really know. Some areas are really devoid of what I would call drinking water.... There are some stock tanks but they can dry up super fast. Some Areas I hunt one trip is just drinking water and horse feed. The elk move in circles, there for a few days then gone the next. I've killed bulls 15 miles in and Ive killed them a mile off the unit border. Please don't bite off more than you can chew, found more than one bull with antlers and backstraps removed, the rest of the bull left to rot because they couldn't get it out in one trip. I think you will be hard pressed to line up a packer as most people that have stock will be guiding, but if you do awesome. I would have a backup plan just in case they leave you high and dry. Some of the FS trails don't really exist anymore due to the burns and flooding FYI. Good luck and enjoy it its an amazing place.
