Book excerpt: "Mortimer chronicles three centuries of inquiry into Lake Michigan from the Native Americans, who called it Michigani (Great Waters), to the French explorers, whose first recorded observations date from the 1600s, to present-day scientists, who use satellite views of the Great Lakes from outer space." "Lake Michigan in Motion is a source of information for amateur naturalists, students, teachers, public officials, a wide variety of scientists and natural resource managers, residents of Lake Michigan's shores, and others who use the lake for their livelihood and recreation."--Jacket.
