Where can I purchase a REALLY good topographical map of the Flat Tops Wilderness Area in Colorado?

My husband hunts and camps there every summer and the group has never been able to find a good map of the area. They use their GPS systems and their heads to navigate the difficult terrain. I'd like to get him one on the internet, but I'm not sure where to start...please help!Where can I purchase a REALLY good topographical map of the Flat Tops Wilderness Area in Colorado?
I think my first choice would be the Trails Illustrated maps from National Geographic. They are good quality topographic maps, and their trail information is relatively current.



Here's their web site for Colorado maps:

Unfortunately, you need four different maps (#122, 123, 124, and 125) to cover the entire Flat Tops Wilderness.



You can buy the maps directly from this web site, or from other stores with outdoor supplies.



The best (but not necessarily current) topographic maps are from the United States Geological Survey; but with their scale of 1:24000 or 1:25000, you'd need a lot of maps to cover the entire wilderness area.

If you want to view the USGS maps from your computer, you can order the TOPO! software for Colorado:

This is useful for exploring by map before or after the trip, but it's not very practical to print out a lot of these maps from your home computer.



A previous answer mentioned the DeLorme maps. These are excellent for exploring an area (including back roads) by car, but they are not adequate for hiking.

Curious_45's recommendation to contact the Forest Service is also good. The Flat Tops are split between two units -- Medicine Bow %26amp; Routt National Forest, and White River National Forest. Here are their web sites for maps:

Maps made by the Forest Service aren't as detailed as the USGS or Trails Illustrated maps, but might have the most current information on facilities such as roads and campgrounds. (Also, Forest Service maps are usually *not* topographic maps, unlike the other maps mentioned above.)
The Forest Service probably has good ones. You would just have to check with them when their office is open or perhaps you could call them. Perhaps they could send you one. Also, there is a company called DeLorme ( or something similar to that) that makes really good maps of western states. They are very, very detailed and show every road, trail etc. Probably a good bookstore or Walmart should carry them. They are around $20 but well worth the price. Each time we move to a new state, we get one. Great help!Where can I purchase a REALLY good topographical map of the Flat Tops Wilderness Area in Colorado?
A hiking or outdoorsman's store? like REI.
