This filmstrip and accompanying text were discovered in the archives of the Iowa Geological Survey in early 2008. A suitable filmstrip projector was not available. The filmstrip itself, believed to date from circa-1971, was deteriorated (see below). The filmstrip was scanned and color restoration was accomplished. This PowerPoint presentation recreates the educational intent of the original filmstrip. For a higher resolution file, please contact the Iowa Geological Survey.
