Kurzbeschreibung des Verlags

"The Origin and History of Extinct Lake Calvin" is a comprehensive geological study by Walter Henry Schoewe that explores the formation and eventual disappearance of a significant Pleistocene glacial lake. Situated in what is now eastern Iowa, Lake Calvin represents a critical chapter in the regional geomorphology of the American Midwest. This work provides a detailed analysis of the lake's boundaries, the glacial forces that shaped its basin, and the sedimentary evidence left behind.Schoewe meticulously documents the drainage patterns and the impact of the Illinoian and Iowan ice sheets on the landscape. By examining topographic features and terrace formations, the author reconstructs the ancient environment, offering insights into the complex interactions between glacial advances and river systems. The text serves as a fundamental resource for understanding the Quaternary period and the post-glacial development of the Mississippi River basin's tributaries.Rich in empirical observation and historical scientific context, "The Origin and History of Extinct Lake Calvin" remains an essential reference for geologists, hydrologists, and students of North American natural history. It stands as a testament to the rigorous field research of the early 20th century, providing a clear window into the forces that defined the modern Midwestern landscape.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
