Ancient Roots of the Windy City Exploring the Geology of Downtown Chicago
Raymond Wiggers, Guide and Author of Geology Underfoot in Illinois
Sunday, July 22
Starting from the Chicago Cultural Center at 9 a.m.
Chicago is world-renowned for its magnificent architectural achievements. But behind these works of genius and their fascinating design history lies another world: the record of Ice Age glaciers, treacherously shifting lakebed sediments, long- vanished tropical seas, and vast forces operating deep in the Earth’s interior.
On this walking tour we’ll explore the unexpected interplay between art, science, civil engineering, and immense geologic time. As we highlight Chicago’s great architects and examine the buildings that made them famous, we’ll come to understand the greater significance of a wide assortment of ornamental stone, brickwork, and terra cotta adornments derived from sources both local and exotic. It’s a trip that will lead us from local stone quarries to the islands of Lake Superior, and from the mountains of Italy to ancient seaways of the Age of the Dinosaurs and even to the distant origins of North America over three and half billion years ago.
Highlights of the tour include explanatory stops at the Chicago Cultural Center, the Auditorium Building, the Monadnock Building, the Aon Center, the Wrigley Building, Tribune Tower, the Magnificent Mile, and the Chicago Water Tower.
