Welcome to the website for my course on Cincinnati geology. This website is a gateway to other pages and sites that provide abundant detail on the fascinating diversity of geology of the Tri-state area, including much information on geologic hazards. The section entitled "Papers" has some longer, more formal presentations on local geology. "Data" has some useful databases. "Illustrations" is a photo collection of important features. Each index page has a group of thumbnail images. Click on the thumbnail to bring up the full-scale image. Finally there is a collection of links to other sites that contain useful information about geology, architecture, and hazards.
