Yeah, too many units and such swiriling around in my head, should have said unit 4 or possibly 441 or 214. Looking at the Routt Nat'l Forest. Just trying to figure it out using the DOW and other websites. Looks like the Craig area is a great elk area, just got to figure out where to hunt.
The Elkhead mountains NE of Craig (units 4, 441, 214) have lots of elk. But for 2nd rifle, they also have LOTS of hunters. I would definitely recommend looking at areas where you can get at least a mile from roads and access points--this will thin the herd of orange considerably.
I'd suggest 3 areas for you to check out. The area south of Bear's Ears has good consistent elk, but it's a hike to get into and out of this area. North of Steamboat lake and Pearl lake is also OK, but you'll see more hunters here. The Western edge of the national forest around Freeman Reservoir is also good for elk numbers usually, but again the number of hunters is high too. I guess the "take home" message is...there's lots of hunters in all of these areas. If you're looking for some solitude, either change the area you're considering or maybe try a 1st rifle, muzzleloader or archery season.
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...
