Welcome!
As state geologist and director of the Iowa Geological Survey, it is my pleasure to welcome you to our website. It’s a great repository for all things related to Iowa geology and water resources, and I’m confident you’ll find a lot of interesting information to browse through. You’ll see that the site is organized around four main pillars of information exchange: research, services, popular interest, and data and resources.
