Nevada, a land of extremes in topography, aridity, and geology, is a vast and wild area, the seventh largest state. Its 109,826 square-mile land area is roughly equivalent to that of the United Kingdom and Denmark. Nevada's rugged, mountainous topography contrasts dramatically with that of most surrounding regions in the western U.S. Its landscapes and geology are very diverse, beautiful, and far more interesting than first meets the eye. Our photos may surprise you! In addition, the geology of Nevada is remarkably complex. Other states will seem tame by comparison. A little geology background, just enough to be dangerous, will enable you to see and understand things you never knew were there. This is a book with captivating scenery, colors, patterns, and landscapes, and some surprising historic vignettes. Additionally, it is a travel companion that will make your Nevada trips more informative and enjoyable and will assist in your exploration and adventure. We present photos, maps, and brief explanations of what you are seeing when you drive through Nevada, from a geological perspective. We have tried to inform you, the traveler, about Nevada's geological resources and geologic history, about human impacts, and the 'law of unintended consequences.' You will share in discovery of many wild places and points of interest, and you may find a few nuggets of information here and there. Because this book is designed for use on road trips, we assume you are a voyager with a companion, your navigator/copilot. While you are driving or stopping to admire a view, your copilot reads, directs, and narrates the scenery and geologic story of Nevada. You will find that the best times for seeing Nevada are early to mid-morning and late afternoon to early evening, when colors and shadows are most dramatic. Join us and enjoy the journey.
