Geology of Minnesota: A Centennial Volume

This extensive volume, published on the 100th anniversary of the Minnesota Geological Survey, was intended to summarize knowledge (as of 1972) of the geology of Minnesota. Organized by historical periods (Early Precambrian, middle Precambrian, late Precambrian, Paleozoic and Mesozoic, and Cenozoic), most sections include an article focusing on the geology of the Minnesota River Valley region.
