176-year history of underground use in Chicago
Dr. Rober A. Bauer (Illinois State Geological Survey, Prairie Research Institute)
This compilation and history of deep utilities started with supplying information to the Boring Company of possible subsurface manmade obstacles to placing two 14-foot diameter tunnels from Downtown Chicago to O’Hare Airport while staying in glacial materials at a depth of about 50 feet. This is a partial display of the many holdings at the Illinois State Geological Survey and public information and images.
