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.

Author Charlie Spencer shows you around the state from the flat, glaciated plains in the north to the knobs of rhyolite in the St. Francois Mountains in the south, and from the earthquake-formed sand boils on the Mississippi floodplain in the southeast to the layers of coal, shale, sandstone, and limestone on the Springfield Plateau and Osage Plains in the west.

Since Mountain Press started the Roadside Geology series forty years ago, southern Californians have been waiting for an RG of their own. During those four decades�which were punctuated by jarring earthquakes and landslides�geologists continued to unravel the complexity of the Golden State, where some of the most dramatic and diverse geology in the world erupts, crashes, and collides. With dazzling color maps, diagrams, and photographs, Roadside Geology of Southern California takes advantage of this newfound knowledge, combining the latest science with accessible stories about the rocks and landscapes visible from winding two-lane byways as well as from the region�s vast network of highways. Join Arthur Sylvester, an award-winning UC Santa Barbara geologist, and Elizabeth O�Black Gans, a geologist-illustrator, as they motor through mountains and deserts to explore the iconic features of the SoCal landscape, from boulder piles in Joshua Tree National Park and brilliant white dunes in the Channel Islands to tar seeps along the rugged coast and youthful cinder cones in the Mojave Desert. Whether you want to find precious gemstones, ponder the mysteries of the Salton Sea, or straddle the boundary between the North American and Pacific Plates, be sure to bring this book along as your tour guide.

From the glacially scoured quartzite ridge that hosts the Appalachian Trail to the spectacular columnar basalt of Orange Mountain, New Jersey packs a boatload of geology into a small area. Its nineteenth-century marl pits were the birthplace of American vertebrate paleontology, bog iron deposits in the Pinelands were used to produce cannonballs for the Revolutionary War, world-famous fluorescent minerals are found with zinc deposits in the Franklin Marble, and the coastal plain sediments contain convincing evidence of the meteorite impact that killed the dinosaurs. This absorbing book opens with an overview of the state�s geologic history and proceeds with 13 road guides that unearth the stories behind the state�s rocks, sediments, and barrier islands. More than just a guide, Roadside Geology of New Jersey is chock-full of insightful discussions on such timely topics as sea level rise, climate change, and uranium mining. Get the scoop on why so much sand moves during superstorms such as hurricane Sandy, and learn about more than a century of efforts to stabilize the beaches along the Jersey Shore.
