Geo-Texas succeeds in bringing together astronomy, geology, meteorology, oceanography, and environmental studies in a highly informative, one-of-a-kind guide to Earth sciences in the Lone Star State. Eric R. Swanson draws on the latest scientific findings in treating the natural history of Texas from the oldest known rock, through the age of the dinosaurs, to the geologic present, from the early development of Texas' water and land resources to the current crisis of environmental pollution. In examining Texas natural sciences-and the abiding connection between Texans and their physical surroundings-Geo-Texas is engagingly anecdotal and draws freely on the wry humor with which Texans have always observed and regarded their environment. Entertaining accounts of natural phenomena, such as a meteorite scoring a direct hit on a swimming pool and a Texas twister sweeping up a farmer and returning him to earth unharmed, supplement the scholarship in each chapter to show how cultural and scientific issues converge. Students and teachers of Texas Earth science will find Geo-Texas indispensable. With more than eighty illustrations and valuable appendices listing rock hound clubs, Earth science organizations, and points of interest throughout the state, Geo-Texas will also appeal to the general reader and serve as the Earth science guide for lovers of Texas and its multifaceted environment.
