Аннотация:This monograph describes the glacial features and the great glacial lakes of a district in Indiana and Michigan lying between the areas covered by Monographs XXXVIII, and XLI. The glacial features are treated mainly by Mr. Leverett, and the glacial lakes and their moraines by Mr. Taylor. The pre-Wisconsin glacial and interglacial formations are given attention, but the principal subject of discussion is the Wisconsin drift of the Saginaw lobe and the neighboring portions of the Lake Michigan and Huron-Erie lobes.
