Upper Sioux Agency State Park

The grounds extend over 1,280 acres along the Minnesota River, featuring prehistoric sites and remains of the former Yellow Medicine Agency buildings.

The U.S. government established the Yellow Medicine Agency in 1854 to implement the Treaty of Traverse des Sioux, managing relations with Dakota tribes.

The land holds deep meaning for Dakota people as a site where their ancestors experienced severe hardships during the summer of 1862.

The Minnesota State Legislature transferred the ownership of all state-owned land within the park to the Upper Sioux Community in 2023.

The Minnesota Department of Natural Resources officially closed the park to public access on February 16, 2024, marking the end of its 61-year operation.
