File:National Forests In Colorado.png
David Benbennick made this map with data from nationalatlas.gov.
The map uses the azimuthal equidistant projection, centered on (-105.7167, 39.1333) (degrees latitude, longitude). The area outside Colorado is transparent, so it should look nice on non-white backgrounds.
Eventually, I will upload the 4 megabyte Metapost script I used to make this map. In the mean time, see map.mp.
