Rocks occur in many different forms, from common and plain to rare and beautiful. Arizona Rocks is designed to provide the user with the basic tools for mineral and rock identification, as well as provide a pictorial guide to some of the more interesting and important types of rocks and minerals found in Arizona. Concise explanations are given for each, including hardness, colors, most common crystal shapes, and unusual features associated with each.
This waterproof, pocket-sized quick reference also contains information on proper collection and documentation of specimens you may find, and rules and regulations concerning such activities. Detailed mineral identification is often accomplished only in a lab, but many rocks and minerals may be identified through the combination of hardness, color, and unusual characteristics presented in this guide. Collectors of every level will find this information helpful. Arizona Rocks is a useful and attractive addition for any rock collecting activity!

David Trexler is a research scientist whose career has focused on dinosaurs and their environments. He and his family are known for major paleontological discoveries including Maiasaura peeblesorum. His current research focuses on comparisons between past and present climate and its effects on animal life.
David was born and raised in Montana. He spent his early years working in his family’s rock shop where he learned rock, mineral, and fossil identification. Growing up along the Rocky Mountain Front, Dave learned firsthand the interactions between geologic, climatic, and biologic processes in a largely undisturbed environment. This background sparked an interest that has continued throughout his career. He always enjoyed sharing his love of rocks and fossils, and in 1985 began teaching field programs for the general public. In 1990, he began teaching college level courses in field paleontology and geology. Dave received dual undergraduate degrees in Biology and Earth Sciences in Montana, and a graduate degree in Vertebrate Paleontology in Alberta, Canada.
A driving force throughout his career has been providing participation in scientific research for the general public. Dave has conducted research and training throughout western North America. He has served as the staff paleontologist for several museums and currently works for the Two Medicine Dinosaur Center in Montana. Dave’s research includes climate and climate change from a paleontological perspective. His work has identified long-term cycles that have a major impact on present day events. A portion of this work is explained in his book, “Becoming Dinosaurs: a Paleontologic Perspective on Climate Change Today.”
