With this book in hand, explore mining districts and fossil reefs in the western mountains, dike-laced granite of Enchanted Rock, springs and caves along the Balcones Escarpment, salt domes and ever-changing barrier islands along the coastal plains, and the layered sedimentary rock of Palo Duro, Seminole, and Santa Elena Canyons.
