It contains some of the oldest rocks on the continent, has a geologic history spanning the greater part of geologic time, and is considered to be one of the classic geologic areas in the world.  The citizens of the three states comprising the region, Minnesota, Wisconsin, and Michigan, as well as tourist to the area and students of geology, have a lasting fascination with the geology, land forms, and lakes as well as with the vast mineral resources of this geologically rich and scenic region.  As a result, there is a continuing demand for well-produced books that describe these features.... This new volume by Gene L. LaBerge deals with the entire Lake Superior region and is a welcome addition to the several excellent earlier books on the general geology of this area.  It is an up-to-date interpretation of the geology that follows on the heels of two decades of intensive study of the oldest rocks in the region, the Precambrian, by Federal and State Geological Surveys and personnel in several universities. The author played a significant role in these studies....The text is written in a clear, understandable style that is easy to read...  The book will be of interest to beginning students in the physical sciences and those involved in solving environmental problems, as well as citizens of the region and tourists... --Economic Geology,Vol. 90, no. 1, 1995The complex geology of the Lake Superior region is one of the most interesting in the United States to mineral and gemstone collectors since it encompasses such treasured specimens as Lake Superior agates, thomsonites, kona dolomite, jaspilite, chlorastrolite, gold, native copper and silver, and many more. Geology of the Lake Superior Region documents the many changes that have caused the scenic area to evolve into the bonanza of collectibles and the incomparable freshwater lake that it is today.The areas surrounding Lake Superior constitute significant portions of the upper Midwest, specifically Michigan, Minnesota, and Wisconsin.
