Book excerpt: Winner of the 2021 Minnesota Book Award for Minnesota Nonfiction The story of the scientist who first mapped Minnesota’s geology, set against the backdrop of early scientific inquiry in the state At twenty, Newton Horace Winchell declared, “I know nothing about rocks.” At twenty-five, he decided to make them his life’s work. As a young geologist tasked with heading the Minnesota Geological and Natural History Survey, Winchell (1839–1914) charted the prehistory of the region, its era of inland seas, its volcanic activity, and its several ice ages—laying the foundation for the monumental five-volume Geology of Minnesota. Tracing Winchell’s remarkable path from impoverished fifteen-year-old schoolteacher to a leading light of an emerging scientific field, Minnesota’s Geologist also recreates the heady early days of scientific inquiry in Minnesota, a time when one man’s determination and passion for learning could unlock the secrets of the state’s distant past and present landscape. Traveling by horse and cart, by sailboat and birchbark canoe, Winchell and his group surveyed rock outcrops, river valleys, basalt formations on Lake Superior, and the vast Red River Valley. He studied petrology at the Sorbonne in Paris, bringing cutting-edge knowledge to bear on the volcanic rocks of the Arrowhead region. As a founder of the American Geological Society and founding editor of American Geologist, the first journal for professional geologists, Winchell was the driving force behind scientific endeavor in early state history, serving as mentor to many young scientists and presiding over a household—the Winchell House, located on the University of Minnesota’s present-day mall—that was a nexus of intellectual ferment. His life story, told here for the first time, draws an intimate picture of this influential scientist, set against a backdrop of Minnesota’s geological complexity and splendor.

Book excerpt: The Early Proterozoic Michigamme Formation of northern Michigan was deposited in the southeastern part of the Animikie basin. The formation conformably overlies the Goodrich Quartzite and comprises three widespread members a lower member of thin-bedded shale, siltstone, and sandstone; the Bijiki Iron-formation Member; and an upper member of tur- biditic graywacke, siltstone, and mudstone and a few local members. The Goodrich Quartzite is interpreted as having been deposited in a tidally influenced shallow marine environ- ment. The lower member of the Michigamme is interpreted as having been deposited in a tidally influenced environment, the iron-formation member as having been deposited below wave base in somewhat deeper water, and the upper member as having been deposited in still deeper water with turbidity currents being a major depositional mechanism. Several lines of evidence including paleocurrents, paleo- geographic setting, and neodymium isotopes suggest that the graywacke of the southern part of the outcrop area was derived from the south (Early Proterozoic Wisconsin magmatic terranes, Archean miniplates, and older Early Proterozoic sedimentary units formed on the continental margin), and that the graywacke in the northern area was derived from an Archean terrane to the north. The tectonic model that best fits the available data is a northward-migrating foreland basin.
