Travelers on Interstate 80 will see that most of Wyoming is high, cold desert, miles of rolling sagebrush, usually with mountains on the horizon. But Yellowstone, the world's first and possibly most famous national park, covers the northwest corner, and just south of it is Grand Teton National Park. Several other high snowy ranges are scattered about, plus the unique volcanic peak known as Devils Tower.

Yellowstone, Teton, the Beartooth Range, the Bighorn Mountains and Devils Tower are all covered in the guidebook to Northern Wyoming. The rest of the state is in Southern and Central Wyoming, rich in the history of the Oregon Trail and the transcontinental railroad.
