CO has a link to interactive maps for all GMUs. You can add whatever filters you want and customize it. This means you can put in things like deer summer range and deer winter range. You can put in roads, camping spots, public lands etc... and the maps can be downloaded. That's the first thing I would do and the second thing is get in touch with the wildlife biologist for that area and pick his/her brain for hunting info. I have found the biologists to be a very good source of info. Take what they tell you and put that info onto the map you made.
