Book Description
Excerpt from An Historical Sketch of the Lake Superior Region to Cambrian Time The ancient formations 'south of Lake Superior may be grouped into five great divisions: the Basement Complex, the Lower Huronian, the Upper Huronian, the Keweenawan, and the Lake Superior Sandstone. These five divisions are separated by unconformities of great magnitude, two of them at least being of the first order. According to the classification adopted by the United States Geological Survey, the Basement Complex is Archean; the Lower Huronian, Upper Huronian and K-ewee nawan constitute the Algonkian for this region; and the Lake Superior Sandstone is Cambrian.

Book Description
Excerpt from "Ne-Saw-Je-Won" As the Ottawas Say: A Tale of the Waters That Run Down From Lake Superior to the Sea Several years ago a group of business men, accustomed to a mid summer trip together on a lake freighter, each day afloat gathered to discuss subjects of mutual interest. One of them, a geologist, con tributed a series of informal talks on the Geology of the Great Lakes Region and the History of the Lakes, drawing illustrations from the rocks and shore features that could be observed from the ship. So much interest was aroused by these discussions that eventu ally it was planned to have the story written in brief, popular form, with the necessary maps and illustrations, so that it could be read at leisure and retained as a memento of such voyages. Years passed without any action being taken on this idea, until in the fall of 1938, Miss Helen M. Martin, geologist, associated with the Michigan Geological Survey, was engaged to prepare the manu script. As she is intimately familiar with the geology of the lakes region and is a former student of Dr. Frank Leverett (who, with the late Frank B. Taylor, is mainly responsible for what is known of the origin and development of the Great Lakes) Miss Martin is especially qualified for this undertaking. In the spring of 1939, her manuscript, sketch maps and photographs were turned over to Mr. M. D. Harbaugh, who has done the editorial work, prepared final drawings, and designed and directed the publication.
