In the consideration of the broader taxonomic aspects of the general geologic section of the rocks of our state two features in particular at once arrest attention. One of these features is the completeness and discrimination with which the glacial deposits have been differentiated so that the Iowa sequence becomes the standard Pleistocene section for this country. This is one of the distinct advancements recently made in American geology. For it credit is due mainly to workers in Iowa and especially to Iowa men.
