Under Michigan : The Story of Michigans 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.

Northwest Exposures: A Geologic Story of the Northwest
The tale of the Northwest's geology began more than two billion years ago when an ancient continent split, creating oceanfront property in what is now western Idaho. Pacific islands mashed into that coastline, making large parts of Washington and Oregon. These events were followed by monstrous volcanic eruptions, catastrophic ice age floods, and mountains rising to an accompaniment of earthquakes.
(Includes California, Idaho, Montana, Nevada, Oregon, Washington, Wyoming and southernmost British Columbia.)

Roadside Geology of Arizona
The rise of mountains and the spread of deserts has marked the geologic history of Arizona. Landscapes that we see today are here because of landscapes of the past, and because of tremendous forces deep within the earth, forces that carry continents into collisions and then drag them apart again, forces of heat and pressure and the slow churning boil of the earth's interior. Landscape features result, too, from more comprehensible, more recent forces: the unending attack of water and wind and frost, the building of volcanoes, the short-term geologic happenings like landslides and rockfalls, earthquakes and floods, and a gopher digging a hole...
