This website describes an ongoing series of inter-related projects with the prime objectives of: 1) Producing 1:24,000 scale Quaternary geologic maps of the metropolitan Detroit, Michigan area, and 2) Developing methods for mapping, classifying and revitalizing urban soils.
The Geoarchaeology of Lake Michigan Coastal Dunes by William A. Lovis; Alan F. Arbogast; G. William MonaghanComplex sets of environmental factors have interacted over the past 5,000 years to affect how changes in climate, temperature, relative precipitation, and the levels of Lake Michigan influence the preservation of archaeological sites in coastal sand dunes along Lake Michigan. As a collaboration between earth scientists, archaeologists, and geoarchaeologists, this study draws on a wealth of research and multidisciplinary insights to explore the conditions necessary to safeguard ancient human settlements in these landscapes. A variety of contemporary and innovative techniques, including numerous dating methods and approaches, were employed to determine when and for how long sand dunes were active and when and for how long archaeological sites were occupied. Knowledge of dune processes and settlement patterns not only affects archaeological interpretations, but it is also consummately important to land planners responsible for managing heritage archaeological sites in the Lake Michigan coastal zone.
Under Michigan: The Story of Michigan's Rocks and Fossils by Charles Ferguson Barker (Illustrator)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.
Geology and Landscape of Michigan's Pictured Rocks National Lakeshore and Vicinity by William L. BlewettMichigan's Pictured Rocks National Lakeshore was established in 1966 to preserve one of the most exquisite freshwater coastal landscapes in North America. Located between Munising and Grand Marais on Lake Superior, the rugged coastline is anchored by the Pictured Rocks cliffs--soaring sandstone fortresses awash with natural pink, green, and brown pigments. While the Pictured Rocks' geologic history is generally well understood by scientists, much of this information is scattered among different sources and not easily accessible to general readers. In Geology and Landscape of Michigan's Pictured Rocks National Lakeshore and Vicinity, William L. Blewett synthesizes published and unpublished information on the park's geologic history and combines it with vivid color photographs, detailed maps, and diagrams of the area. Blewett examines the history and geology of the very ancient Precambrian, Cambrian, and Ordovician components of the Pictured Rocks dating back hundreds of millions of years, as well as the much younger unconsolidated Pleistocene (ice age) and Holocene (warm period since the ice age, including the modern landscape) sediments mantling the bedrock, most of which are no older than 12,000 years. He also details the history of the Lake Superior basin, tracing the events that shaped the modern shoreline from ancient times. For visitors to Pictured Rocks National Lakeshore, Blewett has provided a detailed mileage-referenced road log to guide readers to the best and most accessible field sites, and, for the more adventurous, includes a day hike keyed to the geology. A comprehensive bibliography and index are also included at the end of the book for further research. While it assumes an understanding of basic geologic principles, the volume is very readable and suitable for students, interested park visitors, and geologists, physical geographers, and those working in closely related fields such as archaeology, biology, ecology, and environmental science.
Lake Erie and Lake St. Clair Handbook by Stanley J. Bolsenga and Charles E. Herdendorf (Editors)Learn about the wonders of Lake Erie and Lake St. Clair in this fascinating and readable book. The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers-anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region-the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: - how Lake Erie was formed through glacial processes - why daily and seasonal weather patterns occur - causes of the water currents and waves - causes of temperature patterns in the lakes - the location of productive reef features - the species of fish and birds found in the area - the importance of the wetlands - the effect of current and past pollution on the aquatic life in the lakes
