Great Lakes Rocks


Book Description

The geologic story of the Great Lakes region is one of the most remarkable of any place on Earth. Great Lakes Rocks takes readers on this fascinating journey through geologic history, beginning with an investigation of the surface features—the hills and valleys, waterfalls and caves, and the Great Lakes themselves—that we encounter on a daily basis. From there the book digs deeper into the past, and readers learn about the amazing techniques geologists have used to reconstruct the events that shaped this region millions and even billions of years before humans set foot on Earth. Throughout, the book gives special attention to the link between the region’s geology and its modern history, including the impacts of geology on settlement patterns as well as the development of industries and the present-day economy. Other discussed topics include natural hazards that are geologic in nature, including earthquakes, floods, landslides, and coastal erosion, as well as information on rocks, minerals, and ancient life seen in fossils. Written for nonspecialist readers, this book provides a detailed but easy-to-follow introduction to the geology of the Great Lakes region, and it is an ideal fit for introductory geology courses, including those aimed at nonscience majors.

Under Michigan


Book Description

An exciting trip below the surface of Michigan's rocks and fossils. Most people recognize Michigan by its mitten-shaped Lower Peninsula and the Great Lakes embracing the state. Underneath the earth's surface, however, is equally distinctive evidence of an exciting history. Michigan rests on sedimentary rocks that reach down into the earth's crust more than fourteen thousand feet--a depth three-and-a-half times deeper than the Grand Canyon. Within these layers of rock rest all sorts of ancient fossils and minerals that date back to the eras when tropical seas spread across Michigan and hot volcanoes flung molten rock into its skies--long before mile-thick glaciers bulldozed over Michigan and plowed through ancient river valleys to form the Great Lakes. Under Michigan is the first book for young readers about the geologic history of the state and the structure scientists call the Michigan Basin. A fun and educational journey, Under Michigan explores Earth's geological past, taking readers far below the familiar sights of Michigan and nearby places to explain the creation of minerals and fossils and show where they can be found in the varying layers of rock. Readers will learn about the hard rock formations surrounding Michigan and also discover the tall mountain ridges hidden at the bottom of the Great Lakes. With beautiful illustrations by author Charles Ferguson Barker, a glossary of scientific terms, and charming page to keep field notes, Under Michigan is a wonderful resource for young explorers to use at home, in school, or on a trip across Michigan.




The Great Lakes Water Wars


Book Description

The Great Lakes are the largest collection of fresh surface water on earth, and more than 40 million Americans and Canadians live in their basin. Will we divert water from the Great Lakes, causing them to end up like Central Asia's Aral Sea, which has lost 90 percent of its surface area and 75 percent of its volume since 1960? Or will we come to see that unregulated water withdrawals are ultimately catastrophic? Peter Annin writes a fast-paced account of the people and stories behind these upcoming battles. Destined to be the definitive story for the general public as well as policymakers, The Great Lakes Water Wars is a balanced, comprehensive look behind the scenes at the conflicts and compromises that are the past-and future-of this unique resource.




Minnesota's Geologist


Book Description

Winner of the 2021 Minnesota Book Award for Minnesota Nonfiction The story of the scientist who first mapped Minnesota’s geology, set against the backdrop of early scientific inquiry in the state At twenty, Newton Horace Winchell declared, “I know nothing about rocks.” At twenty-five, he decided to make them his life’s work. As a young geologist tasked with heading the Minnesota Geological and Natural History Survey, Winchell (1839–1914) charted the prehistory of the region, its era of inland seas, its volcanic activity, and its several ice ages—laying the foundation for the monumental five-volume Geology of Minnesota. Tracing Winchell’s remarkable path from impoverished fifteen-year-old schoolteacher to a leading light of an emerging scientific field, Minnesota’s Geologist also recreates the heady early days of scientific inquiry in Minnesota, a time when one man’s determination and passion for learning could unlock the secrets of the state’s distant past and present landscape. Traveling by horse and cart, by sailboat and birchbark canoe, Winchell and his group surveyed rock outcrops, river valleys, basalt formations on Lake Superior, and the vast Red River Valley. He studied petrology at the Sorbonne in Paris, bringing cutting-edge knowledge to bear on the volcanic rocks of the Arrowhead region. As a founder of the American Geological Society and founding editor of American Geologist, the first journal for professional geologists, Winchell was the driving force behind scientific endeavor in early state history, serving as mentor to many young scientists and presiding over a household—the Winchell House, located on the University of Minnesota’s present-day mall—that was a nexus of intellectual ferment. His life story, told here for the first time, draws an intimate picture of this influential scientist, set against a backdrop of Minnesota’s geological complexity and splendor.




Minnesota's Geology


Book Description

Have you ever wondered how the Mississippi River was formed? Or why shark teeth have been found in the Iron Range of the Upper Midwest? Towering mountain ranges, explosive volcanoes, expansive glaciers, and long-extinct forms of both land and sea life were an important part of Minnesota's ancient history. Today the evidence of this remarkable heritage is revealed in the state's rocky outcroppings, stony soils, and thousands of lakes.




The Living Great Lakes


Book Description

The author provides an account of his experiences as a crew member on a tall-masted schooner during a six-week voyage through the Great Lakes, and discusses his other explorations of the lakes, looking at their history, geology, and environmental disaster and rescue.
