In lieu of an abstract, here is a brief excerpt of the content:

xiii mmeasurable thanks are due to Gregg Bruff, chief of Heritage Education at Pictured Rocks National Lakeshore, who provided the initial inspiration for this book and shared access to innumerable National Park Service photographs and related documents. Likewise, Dr. Walt Loope of the U.S. Geological Survey was extremely generous in sharing materials on the Holocene history of the park, including the many fine photographs found in chapter 5. He also reviewed an earlier version of the entire manuscript and saved me from many embarrassing blunders. Dr. John Anderton of the Department of Geography at Northern Michigan University read large portions of the manuscript, including all of chapter 5, and corrected me on a number of key points related to coastal landforms, park archaeology, and the Sawmill Culture. Dr. Sean Cornell, my geoscientist colleague in the Geography–Earth Science Department at Shippensburg University of Pennsylvania, served as my hard rock geology expert throughout the writing of the book and patiently answered my annoying questions related to the Precambrian and Paleozoic geology of the midcontinent. He also reviewed an earlier version of the entire manuscript. Thanks also to the two anonymous outside reviewers who performed extremely thorough evaluations of the entire manuscript, and to two anonymous reviewers from the Great Lakes Books Series Editorial Board. Their thoughtful comments improved the book significantly. The National Park Service, through its “Geoscientist-in-the-Parks” program, provided lodging and logistical support for four months at Sand Point during the fall of 2004. They also offered me free reign of the park library, where I was able to examine many of the more obscure and hard-to-find reports on park geology, ecology, and natural history. These efforts were augmented by a grant from Eastern National Corporation (the company that runs National Park Service book stores east of the Mississippi River), which supported the writing of a park service Resource Report that is the basis for chapter 3. My academic home, Shippensburg University of Pennsylvania, provided me with a sabbatical leave in fall 2004 as well as a generous professional development grant in 2007 to support field work and the actual writing Acknowledgments I xiv Acknowledgments of the manuscript. Chapter 4 is based on a Resource Report written in 1994 that was supported by several additional grants provided by the Pennsylvania State System of Higher Education and my university. I am also grateful for the many kindnesses, both large and small, offered by so many people during the preparation of this book. Kathleen Weessies of the Michigan State University Library and Julie King of the Library of Michigan’s Rare Book Room were instrumental in securing a digital version of figure 2.21 from Foster and Whitney’s 1851 report. Shippensburg’s Geography Department secretary Judy Ferrell performed innumerable administrative tasks with her trademark spirit of helpfulness and good cheer, while Shippensburg University graduate student Kaja Spaseff assisted with early versions of some of the graphics. Diane Kalathas of the Shippensburg University library helped me locate a number of hard-to-find references. My departmental colleague Dr. Scott Drzyzga helped me with several technical issues related to the graphics. Thanks are also due to Drs. Randy Schaetzl and Dave Lusch of Michigan State University for encouragement and sharing of materials, to Lou Waldock and Tony Williams for permission to use their photographs in figures 5.9 and 5.17 respectively, and to Brenda St. Martin, administrative assistant at Pictured Rocks National Lakeshore, who let me abuse the copier at park headquarters and never turned me in. A special thanks to all of the crew at Wayne State University Press, whose professionalism, skill, and good sense have made this book better than it was ever destined to be. Of special note are editor-in-chief Kathy Wildfong, who shepherded the book through its initial review; assistant editorial manager Carrie Downes Teefey; assistant design and production manager Maya Rhodes; and the sales and marketing team of Emily Nowak, Sarah Murphy, and Jamie Jones. Freelance copyeditor Dawn Hall was an extremely efficient taskmaster and caught more mistakes than I ever thought possible in the Age of Spellchecker. Freelancer Jane Henderson created an excellent index. Most of all, I am indebted to the small group of scientists whose work forms the basis for our present understanding of Pictured Rocks National Lakeshore. These include Bill Hamblin, Charles Haddox, Bob Dott, John Hughes (my former professor at Northern Michigan University), Walt Loope, Tim Fisher, John Anderton, Chris Drexler, and the late...
