Human Use
The earliest known humans at Silver Mound were Paleo-Indians, who entered the area about 9550 BC. This is not long after the last glacier began retreating a short distance to the north, when the climate remained cool and mammoths and mastodons still roamed the area. To hunt them, the Paleo-Indians needed good projectile points. They also needed knives and scrapers for processing their kill. These tools could be made from the quartzite from Silver Mound, which was the largest source of orthoquartzite in the Midwest. Tools made from Hixton orthoquartzite and datable to this period have been found as far away as Mammoth Cave in Kentucky.
Later Indians continued to quarry the quartzite at Silver Mound. By 8,000 BC the mammoths and mastodons were extinct, but Archaic Indians needed points to hunt large, now-extinct bison, elk and deer, and some quarried orthoquartzite at Silver Mound. Later Woodland and Oneota peoples also used stone from Silver Mound.
In total there are about one thousand quarry pits on the mound. From the fragments left, some areas have been identified as workshops where the larger pieces of quartzite were broken up into smaller pieces suitable for working. In other workshops the smaller pieces were finished. Six rock shelters have also been found on the bluff. Two contain rock art.
Euro-Americans have been aware of the Indian quarries on the mound since the 1840s. It was named Silver Mound because they mistakenly believed it contained silver. Some mining was done, but no silver was found. The land around the base of the mound has been farmed for years, but much of the mound itself remains largely undisturbed. Professional archeologists first visited the mound in 1928. Gradually the remarkable age of some of the Indian quarries emerged. In 1975 Silver Mound was placed on the National Register of Historic Places. In 2006 it was named a National Historic Landmark, largely because of the potential information it may still hold about the earliest people in Wisconsin.

Famous quotes containing the word human:
“Allowing our government to kill citizens compromises the deepest moral values upon which this country was conceived: the inviolable dignity of human persons.”
—Helen Prejean (b. 1940)
“We must trust infinitely to the beneficent necessity which shines through all laws. Human nature expresses itself in them as characteristically as in statues, or songs, or railroads, and an abstract of the codes of nations would be an abstract of the common conscience.”
