Montana is a showcase for some of the most spectacular natural vistas. Ranges like the Bridgers and the Tobacco Roots offer powerful testimony to the strength and natural history of the entire mountain chain. In these mountain valleys one can find ample evidence of the history of European exploration's first tentative ventures into the west. Named after powerful political figures these valleys converge at the headwaters of the mighty Missouri River. Explored and named by the Lewis and Clark Expedition the Madison the Gallatin and the Jefferson rivers add a serene contrast to the ruggedness of the surrounding landscape. Let’s venture underground to an environment that is no less majestic and no less alive than the surface of this spectacular region. Named after those first hardy explorers Lewis and Clark Caverns is one of the finest examples of a living ever-changing cave ecosystem.
