Pete co-authored a new general-audiences publication on Iowa's Landforms and Geology (pdf) as part of the Iowa's Nature series, produced by ISU Extension and Outreach. The Iowa's Nature series represents a complete update to the 1990's publication series by the Iowa Association of Naturalists, and includes ten articles covering numerous aspects of Iowa's natural history and resources. Co-authors on the Landforms and Geology article were Dr. Beth Caissie, now of the United States Geological Survey, and Matt Graesch of the Iowa Department of Natural Resources.
