Ongoing investigations in the unglaciated Driftless Area of southwestern Wisconsin are utilizing two relatively new digital information tools: Lidar and D-Stretch. Processing of Lidar coverage for the Bad Axe Valley reveals that half of the 42 effigy mounds first reported in the 1880s remain intact, and twice as many others have been discovered. The increased density of mounds known for this valley supports a proposed border between Eastman and Lewis and Eastman phase effigy mound groups in that region. D-Stretch applications have revealed new pictograph details that allow reinterpretation of selected sites, including the famous “Red Horn” panel at the Gottschall Rockshelter.
