An Illustrated Presentation of the Architectural Geology of Chicago
by Raymond Wiggers, Geologist and Author, Geology Underfoot in Illinois
What on Earth does geology have to do with the world-renowned architectural masterpieces of the Chicago region? Raymond Wiggers explains the fascinating and often surprising links between science, art, and engineering of our region’s most famous buildings, the materials they’re made of, and the soil, clay, and bedrock they’re anchored in. In this richly illustrated talk, Mr. Wiggers provides fresh perspective on both the vast sweep of geologic history and the origin and use of ornamental brick, terra cotta, molded and fired by skilled local artisans, and a rainbow spectrum of cut and polished stone – some of which is over three and a half billion years old. Special emphasis is placed on such well-known landmarks as the Chicago Water Tower, the Wrigley Building, many of the Loop’s skyscrapers, and a wide selection of venerable suburban structures, from the North Shore to the Fox River valley and the Joliet area.
