Quantitative and qualitative study of stream,-profile data is used to infer recency of uplift which grossly correlates with rates of seismicity.

Chicago in Stone and Clay explores the interplay between the city's most architecturally significant sites, the materials they're made of, and the sediments and bedrock they are anchored in. This unique geologist's survey of Windy City neighborhoods demonstrates the fascinating and often surprising links between science, art, engineering, and urban history. Drawing on two decades of experience leading popular geology tours in Chicago, Raymond Wiggers crafted this book for readers ranging from the region's large community of amateur naturalists, "citizen scientists," and architecture buffs to geologists, architects, educators, and other professionals seeking a new perspective on the themes of architecture and urbanism. Unlike most geology and architecture books, Chicago in Stone and Clay is written in the informal, accessible style of a natural history tour guide, humanizing the science for the nonspecialist reader. Providing an exciting new angle on both architecture and natural history, Wiggers uses an integrative approach that incorporates multiple themes and perspectives to demonstrate how the urban environment presents us with a rich geologic and architectural legacy.
