RSVPs are not required; Midewin's webinars are accessible to 1,000 participants. This is a Midewin program. 

What's it all about? A 1-mile-thick glacial ice sheet moved over Illinois 15,000 years ago and left its mark on Midewin. Environments in prehistoric times included tropical swampland's and subtropical oceans. During this webinar, we will hear about the rocks, hills and plains at Midewin that still bear evidence of these vastly different environments.
