I will be hunting there in two days and have researched this very question. Cabela's Recon Hunt for $3 and Public Lands Layer for $10/year will do it in real time on an iPhone. I suggest caching maps in advance as cell coverage will be poor many times there.
In addition, there is a Google Earth KML file that has all of the Colorado public land boundaries in it. I absolutely love that one, it is so useful to plan and "computer scout" before the trip.
The site is
http://www.nrel.colostate.edu/projects/comap/google_earth.html but there is no current KML. I still have v.7 which appears accurate in all places relevant to me so far.
P.S. I was there scouting during the archery season and heard 4 bulls from the top of the ridge at Jensen SWA. Did not see any but I spent all of 2 hours on site. A friend tells me that their success rate on first rifle season was 75%.
