During the last year work on the geology of southwestern Iowa has been continued. The different outcrops in the vicinity of Stennett in Montgomery County have been visited, and important information obtained of the stratigraphy and paleonology of the Stennett limestones and the Braddyville and Platte shales. In Fremont County the exposures at Hamburg, McKissicks Grove, Mill Creek, as well as those from Opossum Creek north to Thurman have again been examined, in hopes to definitely locate the break that takes place in the strata between Thurman and the Wilson section
