Utah has more than its share of natural treasures, with Zion and Bryce Canyon national parks and the other wonderful red-rock areas of southern Utah springing to mind first. But tucked away in the state's far northeastern corner, more rugged and less accessible, lies a playground of great scenic beauty, filled with fascinating historic (and prehistoric) sites. And you won't have to fight throngs of tourists here: This land where the dinosaurs once roamed is still relatively undiscovered and unspoiled.
