Midwestern Geology And Cornell College: The First 125 Years, Gene E. Hinman, Paul L. Garvin Jan 1997

Midwestern Geology And Cornell College: The First 125 Years, Gene E. Hinman, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

The history of geology at Cornell College can be traced back almost to the college's beginnings. Though not the first to reach geology at Cornell, William Harmon Norton, more than any other person, shaped the Department of Geology and set it on its course of excellence. Born in 1856, the son of a Methodist minister, Norton developed an ardent interest in geology in his boyhood. A graduate of Cornell in Classics, Norton was hired by his alma mater in 1876 to reach Greek, bur his avocation was geology. He spent most of his spare time on weekends and during ...


The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson Jan 1997

The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson

Journal of the Iowa Academy of Science: JIAS

Johan August Udden served on the faculty of Augustana College from 1888 until 1911. His research during that time was directed toward an understanding of the geology of areas close at hand, the region around Rock Island and nearby areas in Iowa and Illinois. Udden's most significant contributions to Iowa geology were in his treatment of 1) Paleozoic, Cretaceous, and Quaternary stratigraphy; 2) subsurface geology, including information on bedrock elevations and topography; 3) characteristics and origin of the loess. Most of this information was included in the Annual Reports of the Iowa Geological Survey published between 1899 and 1903 ...


Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker Jan 1992

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial ...
