The whole central portion of 231 is routt national forest, so land access shouldn't be an issue. If your hunting late in the season, i'd stay lower in elevation, 10k ft at ripple creek is most likely too high for the elk later in the season, especially if it has snowed.
good luck, routt and white river are nice areas, some areas (like trappers lake) south out of 231 have been hit hard by fires in recents years.
I hunt 231 every year actually. Mostly for elk. Last year I got a big 6x6 bull. Just got back from up there yesterday. Got another good size bull but it is just a 5x5. Not bad though because I'm in it for the meat mostly. As far as deer go, I have seen some monster bucks up there. Just not a real fan of the taste of deer from the hills compared to deer from the plains out in the eastern Co plains.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
