71. Utah - Nine-Mile Canyon, Bonneville Salt Flats, and Canyonlands National Park

Following the Nine-Mile Canyon road to the Book Cliffs, we look for a rugged canyon wall covered with more than 10,000 intricate petroglyphs. Next, we race across a salt desert and try to set the fastest land-speed records. Lastly, about a five-hour drive from the salt flats takes us to Moab, Utah, where we stop at an underrated national park to view its diverse spectacular landscape.
