A 1970s aerial photograph of the Marching Bear group of mounds. An archeologist and students from Luther College in Decorah had outlined the mounds with agricultural lime so they could be visible and photographed from a plane overhead. The portion of trail shown in the photo is the old military road that existed between Fort Crawford in Wisconsin and Fort Atkinson in Iowa. Today, that section continues to be used as the hiking trail to the Marching Bear mounds. Photo courtesy of Effigy Mounds National Monument, National Parks Service
