CEDAR FALLS, Iowa -- The Tallgrass Prairie Center at the University of Northern Iowa will host Art Bettis, associate professor of geoscience at the University of Iowa, at 4 p.m., Wednesday, Jan. 25, as part of the center's ongoing seminar series. The Tallgrass Prairie Center is located on the UNI campus at 2412 W. 27th St. 

Bettis will speak about the geologic history of the Upper Mississippi River Valley and its value in flood plain restoration.  The shaping of the Upper Mississippi River Valley, from the Twin Cities to just above the junction with the Ohio River, has been extensively studied and mapped for several decades.  Bettis will outline the process that formed the landscape of the Mississippi River Valley during the last glacial period and over the past 10,000 years. He will also discuss why restoration plans should incorporate existing information about the valley's formation to develop cost-effective projects and management practices.

Bettis is the coordinator of the University of Iowa Environmental Science Program.  His research focuses on landscape evolution over the past 2 million years. He pursues interests in the long-term behavior of wind, water and glacial systems and the impact of human activities on the landscape.
