Park Scientists: Gila Monsters, Geysers, and Grizzly Bears in America's Own Backyard

Gr 4–8—This entry in this popular series focuses on the study of selected plants, animals, and geologic formations in three of our most famous national parks, which are akin to "natural laboratories and living museums." It all begins in Yellowstone National Park, where hydrothermal activity and its effects are astutely explained. Next, the history, current status, and study of the famous park grizzly bears are carefully detailed. Exploration and examination of giant saguaro cacti and the elusive Gila monster are the focus in the section on Saguaro National Park, which includes a description of "BioBlitz" through which everyday citizens and students can assist in park research programs through 2016. The Great Smoky Mountains is home to more than 30 species of salamanders, and they, plus the equally fascinating fireflies of the region, are targeted in the final chapters. Pertinent, attention-grabbing, full-color photographs and captions, maps, infrared images, and diagrams accompany the fascinating, informative text in each section. Featured experts provide primary-source information for each topic covered. The introductory map of all national parks is missing two in Colorado, but that is a quibble. Overall, this is a well-written, unique, carefully organized treat for nature lovers and investigators.—Diane P. Tuccillo, Poudre River Public Library District, CO
