I-70 is the speedway that gets you across Utah, but to dip into southeastern Utah, you'll need to use the main artery, U.S. 191, which runs south toward the Arizona border. The only road that stretches any distance westward across the region is Route 95, which dead ends at Lake Powell. No matter which of the state roads you use to explore the area, you're in for a treat. Here the earth is red, purple, and orange. The Manti-La Sal Mountains rise out of the desert like ships. Mesas, buttes, and pinnacles interrupt the horizon in a most surprising way. But this is some of the most remote country in the United States, so services are sometimes far apart.
