Thanks to the Illinois Geographic Alliance and Illinois State University, Illinois AP geography classrooms have a wonderful, interactive resource for exploring their home state. Lesson plans and detailed maps of boundaries, demographics, cities, Amtrak routes and much more are included on the Online Atlas of Illinois website. In addition, the Atlas is a superb example of an ArcGIS Online story map. Visit the following link to see for yourself!
