Excerpt from Physical Features and Geologic History of Des Moines Valley<br/><br/>Purpose of this Report  The aim of this report is to describe the important features of the valley of Des Moines river and to discuss as well the geologic history and structure of the region in which the valley is situated. The motive in undertaking this work has been to make avail able for study and general use a simple and yet comprehensive outline of the characteristics of a typical Iowa river and its valley. A study of this kind should be of value and interest in widening and intensifying the knowledge of Iowa geography and geology, especially among Iowa people. Area, Included.  This study is not intended to be carried far beyond the immediate valley of the river, nor is it the intent to include the entire drainage basin, but rather the valley in its more restricted sense. Only the lower courses of tributary streams are considered. The broader view is left for a later, more inclusive survey. Plate XXVII will show the general relations of Des Moines valley and the region which it crosses. Des Moines river aids in the drainage of three states. Its two forks, the East and the West, rise in the lakes and prairies of southwestern Minnesota and unite their waters below the town of Humboldt, Iowa. In the last few miles of its course it divides Iowa from Missouri and the irregular triangle included between the Des Moines and the Mississippi is the southernmost land of Iowa.
