Description

Most people recognize Michigan by its mitten-shaped Lower Peninsula and the Great Lakes embracing the state. Underneath the earth’s surface, alternatively, 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 varieties 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 provide an explanation for the creation of minerals and fossils and show where they may be able to be found within the varying layers of rock. Readers will learn about the hard rock formations surrounding Michigan and also discover the tall mountain ridges hidden on the bottom of the Great Lakes. With beautiful illustrations by writer Charles Ferguson Barker, a glossary of scientific terms, and charming page to keep field notes, Under Michigan is a superb resource for young explorers to make use of at home, in school, or on a commute across Michigan.
