The TdS Name

The Traverse des Sioux Library Cooperative is named for the point along the Minnesota River at which Native American Indian trails crossed, and for the site of the signing of the Treaty of Traverse des Sioux. This historic 1851 Treaty opened 19 million acres of Dakota land west of the Mississippi River to white settlement.
