In this a previous post (http://2raising4.blogspot.com/2009/07/pbs-show-walking-great-divide-and.html) I described a PBS show that showed how you can walk the continental divide.
In a recent Men's Health Issue, which I am receiving free (disclaimer), there was a short blurb about how you can ride your bike on part of the trail. You can get maps here: http://www.adventurecycling.org/routes/index.cfm. For the section from Butte to Jackson Hole, it required two maps for $15 each.
What do you see?
