Silver Mound is a sandstone hill in Wisconsin where American Indians quarried quartzite for stone tools. Tools made from Silver Mound's quartzite have been found as far away as Kentucky. The oldest have been dated to around 11,000 years ago, so they provide clues about the first people in Wisconsin. Silver Mound Archeological District was declared a National Historic Landmark in 2006.[2]
