Elk move north into Wyoming or near the Co border in November. Exactly when depends on the weather and amount of snow. 4th Rifle this year starts November 17th so it's kinda late compared to last year. Don't bother with the southern part of the unit. It will have snow and access because of snow will likely be very limited. Try your luck around Bull Mountain, if you can get up there. Or the north western part of the 80C road... I doubt you will even be able to get much south of 4 corners. But again, depends on the weather.
We hunt 7 occasionally, but earlier. I bought a leftover tag for my son last year, 4th season that started on November 11th. We had a weekend to kill and I thought it would be a good scouting trip if nothing else. Lots of snow and tough to get around. No elk but a few deer. Personally I'd try trading it for a 2nd or 3rd season tag especially with it being so late this year. There will be lots more elk in the country and you will be able to get around much better... Bull Mountain is always good if you get away from the roads... Good luck!
