Geologic maps supply a wealth of information about the surface and shallow subsurface of the earth. The types of materials that are present in a location and the three-dimensional structure of the bedrock both can be gleaned from a clearly prepared geologic map. Geologists, civil and environmental engineers, land-use planners, soil scientists, and geographers commonly use geologic maps as a source of information to facilitate problem solving and identify the qualities of a region. Maps reveal the position of many types of natural hazards, indicate the suitability of the land surface for various uses, reveal problems that may be encountered in excavation, provide clues to the natural processes that shape an area, and help locate important natural resources. Suitable for lab courses in structural geology as well as field geology work, Spencer describes representative examples of features found on geologic maps and outlines procedures for interpretation and projection. Geometric techniques are explained using a step-by-step approach. Coverage of mapping methods includes tools that provide necessary data, such as Google Earth, GPS, GIS, LiDAR maps, drones, and aerial photographs. Challenging and engaging exercises throughout the text involve students in the mapping process and stimulate an appreciation of the extent and precision of information presented in geologic maps. Regional geology is an important component of lab and field mapping projects. As such, the Third Edition includes new maps of the Gulf of Mexico Coastal Plain, Rocky Mountain Front Range, Yellowstone region, Moab, Utah, Shenandoah National Park, and Hawai’i. A new chapter devoted to tectonic maps also broadens students’ exposure. Ed Spencer brings over 45 years of teaching experience to the text along with valuable insight and clarity into the interpretation and preparation of geologic maps.
How were the Appalachian Mountains formed? Are the barrier islands moving? Is there gold in the Carolinas? The answers to these questions and many more appear in this reader-friendly guide to the geology of North Carolina and South Carolina. Exploring the Geology of the Carolinas pairs a brief geological history of the region with 31 field trips to easily accessible, often familiar sites in both states where readers can observe firsthand the evidence of geologic change found in rocks, river basins, mountains, waterfalls, and coastal land formations. Geologist Kevin Stewart and science writer Mary-Russell Roberson begin by explaining techniques geologists use to "read" rocks, the science of plate tectonics, and the formation of the Carolinas. The field trips that follow are arranged geographically by region, from the Blue Ridge to the Piedmont to the Coastal Plain. Richly illustrated and accompanied by a helpful glossary of geologic terms, this field guide is a handy and informative carry-along for hikers, tourists, teachers, and families--anyone interested in the science behind the sights at their favorite Carolina spots. Includes field trips to: Grandfather Mountain, N.C. Linville Falls, N.C. Caesars Head State Park, S.C. Reed Gold Mine, N.C. Pilot Mountain State Park, N.C. Raven Rock State Park, N.C. Sugarloaf Mountain, S.C. Santee State Park, S.C. Jockey's Ridge State Park, N.C. Carolina Beach State Park, N.C. and 21 more sites in the Carolinas!

The Appalachian Mountain chain to which the Appalachian Trail is anchored are America's classic mountains, featuring pieces of almost every major geological event in Earth's history. This amateur geologist (a chemical engineer by occupation) walked the entire trail over a period of more than 10 years, looking at the manifestations today of events millions of years ago-through a hiker's eyes. This book, reviewed before publication by three top academics in the field, provides background on the development of the rocks beneath the hiker's feet, with layperson-friendly maps and photographs.
A Guide to the Rocks, Landscape, Geologic History, and Settlers of the Area of Big Bend National Park.
"To discover astonishing rocks and landforms in the Beaver State, all that is required is a good map, a sense of adventure, and Oregon Rocks, a guide to 60 of the most compelling geologic sites in the state. The well-chosen destinations span the state's geologic history from the Triassic marble at Oregon Caves to the 240-year-old lava dome on Mt. Hood. With more active volcanoes than any other state in the Lower Forty-Eight, Oregon boasts towering behemoths, steaming fumaroles, and eroding cinder cones. Geologist Marli Miller will guide you through the ash and lava from recent eruptions to find evidence of older ones, including a supervolcano possibly produced by the Yellowstone hot spot before it tracked east, and lava that flowed all the way to the coast from eruptions near the Oregon-Idaho border. Although residents of eastern and western Oregon may not admit they have anything in common, the barnacled sea stacks near Cannon Beach and Tillamook are composed of the exact same rock as stacked lava flows on the Columbia Plateau. With beautiful photographs and informative figures and maps, this guidebook will unite Oregonians in their pursuit of outdoor exploration, be it rock hounding, peak bagging, beachcombing, or contemplating their place in the long history of the Earth"--
Properly understanding and characterizing geologic materials and formations is vital for making critical engineering decisions. Identifying and classifying rock masses and soil formations allows reasonable estimation of their characteristic properties. Comprising chapters from the second edition of the revered Geotechnical Engineering Investigation
In the course of the hundreds of Rio Chama rafting trips that we've logged during the last 30 years, none of us has ever had a bad trip. Such is the magic of the Rio Chama. No matter the weather, the water level, the season, the crowded Big Eddy boat ramp on a blistering Sunday afternoon, or even the coffee forgotten at home, the Rio Chama remains "The People's River." Its stunning beauty, plus its exceptional camping, user-friendly whitewater, and mostly predictable flows, combine to create one of the Southwest's premiere, multi-day, river running experiences.The spectacular, towering canyon walls of the Wild & Scenic section through the remote Chama River Canyon Wilderness is New Mexico's own "Grand Canyon." The geology of the Rio Chama is so exceptional that this river is ideally suited for a river guide with a geological theme. And so, following the release of the Rio Grande geologic river guide in 2011, we turned our (part-time) attention to the Rio Chama. Although most Rio Chama recreation is focused on the El Vado to Big Eddy stretch, thedecision was easily made to include the entire boatable section, from the highlands in Colorado to the confluence with the Rio Grande, as each section of the river displays its own visual spectacles and assortment of adventures. Plus, the geology is magnificent and diverse along the entire length of the river.
