I've been to Region G in Wyo. On average deer densities are a lot higher than the high alpine country I've been to in Colo. From what I've seen in G the deer head down into the trees after the first few days of opening rifle....in response to hunting pressure. I would search for the steepest, roughest, most isolated spots without any trails in that country. A word of advice....many of the bowls end up in cliffs and it's nearly impossible to cross bowls in some of that cliffy country!
In Colo deer densities are super low. There are usually only a few deer scattered over miles and miles of high alpine country. Many of the bachelor groups of bucks head into the trees as soon as they start shedding velvet. That may take place before the early rifle hunts take place. There is a reason why Colo early rifle hunts don't take many pts to draw.
There is generally a super high learning curve on these hunts! It may take several trips and lots and lots of miles before you start to figure things out! One thing for sure, high alpine country is gorgeous....enjoy!
