Book Description
The origin of the Carolina Bays presents a formidable puzzle for geologists and astronomers. The elliptical bays with sandy rims look like they were made by huge impacts, but they do not have the characteristic markers associated with extraterrestrial impacts. The dates of the terrain on which the bays are found span millennia, forcing scientists to conclude that the bays must have been made by the action of wind and water over the last 140,000 years. A new geometrical survey has found that the Carolina Bays are perfect ellipses with similar width-to-length ratios as the Nebraska rainwater basins. This book starts from the premise that if the Carolina Bays are conic sections, they must have originated from oblique conical cavities that were transformed by geological processes to their current form. Mathematical analysis following this line of reasoning provides clues supporting the idea that the Earth was hit during the ice age by an extraterrestrial object. The impact may have triggered the Younger Dryas cold event and caused the extinction of the North American megafauna and the Clovis culture. The Carolina Bays are the remodeled remains of oblique conical craters formed on viscous ground by secondary impacts of glacier ice boulders ejected from the primary impact site.

Book Description
Venture off the beaten path down forgotten roads and discover where a hidden South Carolina exists. Time-travel and dead-end at a ferry that leads to wild islands. Cross a rusting steel truss bridge into a scene from the 1930s. Behold an old gristmill and imagine its creaking, clashing gears grinding corn. See an old gas pump wreathed in honeysuckle. Drive through a ghost town and wonder why it died. When's the last time you saw a country store's cured hams hanging from wires? How about a vintage Bull Durham tobacco ad on old brick? Author Tom Poland explores scenic back roads that lead to heirloom tomatoes, poke salad, restaurants that were once gas stations, overgrown ruins and other soulful relics.

Book Description
San Francisco Bay is the largest and most productive estuary on the Pacific Coast of North America. It is also home to the oldest and densest urban settlements in the American West. Focusing on human inhabitation of the Bay since Ohlone times, Down by the Bay reveals the ongoing role of nature in shaping that history. From birds to oyster pirates, from gold miners to farmers, from salt ponds to ports, this is the first history of the San Francisco Bay and Delta as both a human and natural landscape. It offers invaluable context for current discussions over the best management and use of the Bay in the face of sea level rise.

Book Description
Inland sand dunes are widespread in North America and are found from the North Slope of Alaska to the Sonoran Desert in northern Mexico and from the Delmarva Peninsula in the east to Southern California in the west. In this edited book, we highlight recent research on areas of inland dunes that span a range from those that are actively accumulating in current conditions of climate and sediment supply to those that were formed in past conditions and are now degraded relict systems. This book will be of interest to researchers and scholars of physical geography, geomorphology, environmental sciences, and earth sciences. Contributions include detailed analyses of individual active dune systems at White Sands, New Mexico; Great Sand Dunes, Colorado; and the Laurentian Great Lakes; as well as the vegetation-stabilized dunes of the Nebraska Sand Hills and the Colorado Plateau. Additional chapters discuss the widespread partially vegetated dune systems of the central and southern Great Plains; the relict dunes of the Atlantic Coastal Plain of the eastern USA; and active and stabilized dunes of the Colorado Plateau and the southwestern deserts of the USA and northern Mexico.

Book Description
A comprehensive and indispensable reference for identifying and appreciating native flora From its summits to its shores, South Carolina brims with life and unparalleled beauty thanks to its abundant array of native and naturalized flora, all carefully documented in this revised and expanded edition of A Guide to the Wildflowers of South Carolina. Dramatic advances in plant taxonomy and ecology have occurred since the guide's publication 20 years ago; new species have been discovered while others struggle to survive in the face of vanishing habitats and climate change. The authors, all experienced botanists, offer essays on carnivorous plants, native orchids, Carolina bays, the roles and effects of fire and agriculture on the landscape, and detailed descriptions of the plant communities throughout the state's major natural regions. This expanded edition catalogs nearly 1,000 species organized by habitat, with descriptions, color photographs, range maps, and comments on pharmacological uses, suitability for garden cultivation, origin of common and scientific names, and conservation status.

Book Description
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.
