In the 8 years I have hunted that area I have come on Elk, Big Horn sheep, Mulies, rattle snakes (A LOT OF SNAKES), Valley Quail, Huns, Chukar and a few Pheasant and sage Grouse. The area is over hunted, but the deeper you go, the better. Most hunters hunt out of the truck off the road. I park and hike in for an all day hunt. Better after the Freeze happens. You dont see Snakes and the birds are on the south side. Catch them early and you can make your limit in a few hours. I have seen coveys of 100 strong out there of chukar. I have only seen 2 Pheasant though. Best of luck.
