Minnesota's lakes may be its most famous features, but the glaciated countryside disguises a much longer history of volcanoes and plate collisions--not surprising when you learn that Minnesota was at the active edge of the fledgling North American continent for several billion years.
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 book begins with an introductory chapter that briefly reviews California's geology followed by a series of road guides with the local particulars. The authors tell you what the rocks re and what they mean. Useful graphics and charts supplement the t
California's geology makes headlines when faults shift, volcanoes puff steam, and coastal bluffs fall into the sea. This book explores the state's recent rumblings and tremulous past with the aid of full color illustrations. Photographs showcase multihued rock, from red chert and green serpentinite to blue schist and gray granite. The geologic information, particularly for the Klamath Mountains, Modoc Plateau, and northern Sierra Nevada, has been updated to reflect new geologic understanding of these complex areas. Features detailed, easy to read color geologic road maps based on the 2010 Geologic Map of California.
Ride along with geologists Pamela Gore and Bill Witherspoon on this extraordinary tour of the Peach State�s varied terrain. In 35 detailed and densely illustrated road guides, the Roadside Geology of Georgia examines Georgia�s fascinating geology and reveals the stories that lie beneath the surface. You�ll be amazed at Georgia�s geological diversity, from its shifting barrier islands along the coast to the sandstone ridges in its northwest corner. At the Cumberland Island National Seashore you�ll find the ruins of Dungeness, the once-magnificent Carnegie estate built of local mineral resources, and encounter wild horses grazing among windswept dunes. In Atlanta, the white whaleback of granite called Stone Mountain will impress you with its protruding �cat�s paw� minerals and stony layers that are sloughing off like the layers of an onion. In the Blue Ridge Mountains you can witness Amicalola Falls, one of the highest cascading waterfalls east of the Mississippi River, and Tallulah Gorge, one the deepest gorges in the eastern United States. And in the iconic Okefenokee Swamp of south Georgia, you�ll wade through the gator-filled blackwater of one of the largest wetlands in North America. With its engaging prose and 250-plus color photos, maps, and figures, Roadside Geology of Georgia takes you beyond the rocks to unearth the billion-year history of the Empire State of the South.
