any one got a map of the great western trail?
http://www.fs.fed.us/r4/sawtooth/gwtmaps.htmJust overview maps - but generally speaking the GWT is better termed a trail network rather than a single trail. In UT some of the trails are non-motorized, some are multi-use. There's a bit of GWT worked into Trans Utah.
There are some .gpx files (or might be in the garmin .gdb format) in the forum on gwt.org. There is a single gpx with many thousands of miles of ATV trail for Utah, most of them in the state. That's a lot of data for a single file (about 10k tracks!) and it's a bear to work with but I do at times.
Edit - maps are here:
http://greatwesterntrail.org/maps/. Looks like they use the .tpo format, it's been a couple of years since I grabbed that file...found an online utility to convert .tpo to .gpx. Lemme know if you need the .gpx - it's big, about 80 MB.
