There's some new recognition for an ancient archaeological site in Wisconsin.
U.S. Interior Secretary Gale Norton announced the designation this week of eleven National Historic Landmarks ... and they include the Silver Mound Archaeological District in Jackson County.
It's located near Alma Center ... and it's considered one of the best examples of a quarry site where people came over thousands of years to gather stones used to make tools. The mound itself is formed by a hard form of cemented sandstone, called quartzite, that was excellent tool-making material because of its strength and ability to hold a sharp edge.
Silver Mound also has a shallow cave, or rock shelter, that was occupied at times over the past 10,000 years.
