Welcome to the Central Region Iowa State Information Page. This site is designed to help you learn about earth science studies underway in Iowa.

The USGS undertakes studies in water, energy, mineral, land, and biological resources and furnished results in printed- and digital-format maps, books, and other products. The scientific information we provide assists in the location, management, development, and protection of natural resources of our Nation and of other countries in which the USGS is a cooperator. Equally important, we supply information that helps minimize or mitigate the damage caused by natural hazards and the damage to the environment caused by human activities or natural processes. All Americans can benefit from the work of the USGS.
