At times in the past\, glaciers have covered more than two-thirds of Wisconsin\, and the area covered by the last glaciation exh ibits excellent examples of glacial topography. Wisconsin was chosen as th e location of the Ice Age National Scenic Trail and the Ice Age National S cientific Reserve mostly for that reason. Our most recent glaciation was t he Wisconsin glaciation\, and it was responsible for many of the glacial l andforms we see today. LOCATION: END:VEVENT END:VCALENDAR
