Paleontologists and geologists have excavated more than 15,000 dinosaur bones from the Cleveland-Lloyd Dinosaur Quarry, making this "predator trap" the densest concentration of Jurassic fossils ever found. Since the quarry's discovery by herders in the 1920s, scores of dinosaur remains have been discovered here, including the oldest fossilized egg. Although many of the bones found in the quarry now reside in museums around the world, a trip to the remote landscape surrounding the quarry pit is worth the journey. The visitor center, which generates its own electricity from rooftop solar panels, has a reconstructed dinosaur skeleton and exhibits about the quarry, and the area has some short hiking trails. The center is 15 miles on a gravel road from the nearest services, so bring food and water and dress for desert conditions. It's 32 miles south of Price: take Highway 10 south to the Cleveland/Elmo turnoff and follow the signs. Bonus for families: free admission for ages 15 and younger.
