Best known for the world-renowned Mayo Clinic, Rochester's rich history holds so much more beyond medical excellence. But why was the world's greatest medical center built virtually in the middle of a corn field in the first place? What happened to the Native Americans in the area? Were there ever bears in Bear Creek? Why are there so many geese at Silver Lake, and how did the Zumbro River get its name? What do the extinction of the dinosaurs and the passenger pigeon have to do with Rochester? Retired Mayo Clinic doctor and Rochester native Paul Scanlon answers these questions and more in this collection of historic tales from Med City.
