The Academy of Natural Sciences of Philadelphia has a new exhibit, Dinosaurs Unearthed, running from October 12, 2013 to March 30, 2014. This exhibit features more than a dozen life-size animatronic dinosaurs, as well as skeletons, fossils, and much more.
A life-size Tyrannosaurus rex (pictured here) welcomes you outside the Academy. The long neck of the Ruyangosaurus towers over the Art of Science Gallery. Inside the exhibit, get up close with a microraptor, a Triceratops, a Velociraptor, and more. The exhibit also contains a dig site for young paleontologists, a Dino Detective touch-screen quiz, chances to control dinosaur movements, and other activities to encourage exciting hands-on exploration.
Pine Creek Gorge, sometimes called The Grand Canyon of Pennsylvania, is a 47-mile (76 km) gorge carved by Pine Creek in Pennsylvania. It sits in about 160,000 acres (650 km2) of the Tioga State Forest and is ~1,280 ft (427 m) from the rim to its deepest point. The brown pathway to the right and parallel to Pine Creek is a Rail Trail. TrailLink information on the Pine Creek Rail Trail.
