Canyon Creek, Unit 46 appx. 35.5 sq. miles, is a mule deer and elk hunt and is trad only for the first week of the season, Aug. 29-Sept. 4.
Trout Creek Mtns, Unit 168R1, not sure how big, maybe 1/5th the entire Whitehorse Unit, but there is plenty of room and is trad only for the whole season. It is a mule deer hunt, plus if you draw, sagegrouse, look at the bird regs. There are also antelope, cougars, coyotes and bighorn sheep, though you're more likely to win Powerball than draw a sheep tag.
I've been to the Trout Creeks 4 times. The biggest issue is that it's a long ways from anything and the weather can be fickle, 2 out of the 4 times I've been chased out by snow. You DO NOT want to be stuck up there. There are deer there, including some dreams are made of, but they seem to be in pockets and you could look for days before getting on them. I got lucky and found a spot that holds deer every time I go. If a guy is in good shape and finds the deer, he can have multiple stalks. Bring good binos and spotting scope, you'll need them. The terrain is steep, sagebrush with patches of aspen, and water in most of the canyons. It is beautiful, rugged country, just be prepared for anything. I've not taken a deer there yet, though plenty of stalks. Most stalks are on your hands and knees, working through the sage, difficult, but fun! If you go, bring among other things, 2 spare tires and plenty of gas, flat tires are the rule and you could do a fair amount of driving to find deer. PM me if you have any other questions! Hope this helps.
