Illinois Geologists

This web page lists geologists in the State of Illinois.  Before visiting any of these Illinois geologists, be sure to verify their address, hours of operation, and appointment policies (if applicable).  An geologist may have ceased operations or moved to a different location, and business hours can sometimes be irregular, especially on and around holidays.  So a quick phone call can often save you time and aggravation.
