Great Divide Mountain Bike Route - 2: "Polaris, Montana - South Pass City, Wyoming - 510 miles";

This section of the Great Divide Mountain Bike Route traverses the broad open spaces of southwest Montana, a part of the state that could easily be responsible for the nickname "Big Sky Country." It also incorporates the short, 72-mile section of the route claimed by Idaho, thirty miles of which are on a rail-trail conversion following the route of the old Oregon Short Line, which was responsible for delivering turn-of-the-century tourists to Yellowstone National Park. The trail then enters Wyoming, cutting between Yellowstone and Grand Teton national parks on the little-traveled Ashton-Flagg Road. The second half of this section takes you through the wild and spectacular Teton country, and winds its way down to historic South Pass City, where thousands of Oregon Trail travelers crossed the Continental Divide.
