Geology of Iowa Videos
The Iowa Limestone Producers Association is fortunate to be able to share and preserve the following voice over PowerPoint presentations created by Dr. Raymond R. Anderson. Until he retired, Dr. Anderson, was a Senior Research Geologist in the Groundwater and Stratigraphic Study Section of the Iowa Department of Natural Resources: Iowa Geological & Water Survey. He was also an Adjunct Associate Professor at the University of Iowa, Department of Geoscience; active participant in the Geological Society of America (national and regional meetings), Iowa Academy of Sciences (Academy President), and Geological Society of Iowa (coordinates field trips); peer reviewer for journals and granting institutions.
During his career he authored numerous books, academic papers and maps, most notably on the Midcontinent Rift System (MRS) in Iowa. Dr. Anderson is also well noted for his expertise on the subject of the Manson impact crater, near Manson, Iowa. This is where an asteroid or comet nucleus struck the Earth during the Cretaceous Period, 74 million years ago. We hope you enjoy the following videos created from his original presentations
