I agree with the comments about camo being unnecessary, BUT, its fun matching up to the country you hunt. That said, the "Wyoming mountains" are a big place. One color won't match up with some areas while perfect for others. Without having actually hunted your area, you are guessing. Regardless, dark greens and blacks in my experience are the best all around hues. Think shadows. That is what you want to be- a block of shadow like any other. You should strive to stay in those shadows while hunting, always. It will make a difference, especially if the elk are spooky. And camo helps when the encounter gets close. It can't hurt anyway. Face camo IMO, is VERY important in close encounters. At close quarters the elk are focusing on your face and eyes. Why? More important than clothing. So do a better than average job there. Use a mirror. Don't leave "bullseyes" of white around your eyes. Joshua
