LAST EDITED ON May-14-06 AT 08:08PM (MST)[p]I hear it more as a deer unit than elk, but there area some good pockets of elk areas too.
If you are looking for advice about which drainage to hunt, get ready for dissapointment, however if you are doing preliminary research, then there are several websites that are helpful. You will have to do some detective work on them, but they will tell you how many hunters for each species and success rates. That will tell you if it is worth checking out further. If it is, get some maps, check out where the public land is, try and figure some areas away from roads, then call the local DOW officer and ask specific questions: "Is the road open, is 'bull mountain' a good area for elk, etc." Ask specific quesions and you will get specific answers, they are usually very helpful.
When hunting unit 70, I would shoot the first legal bull you see. Lots of elk in the area, but big bulls are pretty rare.
I realize that a lot of the info you can get from these websites is about drawing a tag for these areas, and you are going on a OTC hunt, but you will also find hunter numbers for each hunt to see how crowed you will be and for the limited hunts for that area (for instance the first rifle season) how many applied, to weigh the demand for that area.

Here is a specific site that breaks down hunters and success of each unit by seasons:
