On the day of the field trip, please plan to arrive at the starting point at 8:15 AM. Each person must sign a liability waiver in order to enter pits, quarries, mines, and other private property. Landowners request this procedure for their protection.  When you register, the required liabiltiy form and optional photo release form will be emailed to you.  In an effort to simplify registration the day of the field trip, we ask that everyone in your party sign, date, and return these forms to the Illinois State Geological Survey before the trip.  The photos release form is optional; we hope to use photos and videos from the field trip on our website and in print materials to highlight the trips.  Please mail forms to Lisa Anderson, Illinois State Geological Survey, 615 E. Peabody Dr., MC-650, Champaign, IL 61820 or if you are able to scan the documents you may email them to  If you are unable to mail or email these forms, please bring them with you the day of the trip or forms will be provided for you that morning.  Thank you for your assistance.

Tours are held rain or shine, no refunds. Wear comfortable clothing and walking shoes and bring along sun-blocking lotion. Bring a hard hat and safety glasses, if you have them, to wear in some places we visit. We strongly advise that you bring insect repellent because some of the places we visit are located in areas of dense vegetation. Bring a packed lunch and drinks, and arrange for your own transportation. The day-long trip ends between 5:00-6:00 p.m.

At the starting point, field trip leaders will direct you to park in line so that the caravan can start out quickly and smoothly after registration. Drivers should begin the tour with a full tank of fuel. If you’re touring on a bus, we recommend only mid-sized (12,000 lbs g.v.w.) or smaller school buses for safe travel on some roads and bridges.
