During the late hunt the elk will have moved down for the most part. I know a few areas
Unit 111
If you are wanting more road access, success loop has plenty of elk, but also plenty of people. The bigger elk, and less pressure, seems to be on the the east side like McCoy Creek, and Cleve Creek.
Unit 115
You have to make sure you are out of the park, but most the elk will be moved out by then. Above the fields seem to be very productive for elk. Murphy Wash Rd and Big Spring Wash are also very good areas on the South side of the range.
If you are planning on hunting the entire 2 week season, take your time and look over the elk. They don’t move much. For the most part they will be in the same spot from day to day. So once you see some bulls be sure to mark them. There’s a high chance they will be there later.
