Site Description:

Settlers began moving west during the mid-1800s into areas that were largely inhabited by Native American Tribes. Leaders of the Yankton Sioux Tribe in southeast South Dakota traveled to Washington D.C. to establish a treaty that would open 11 million acres of land to non-Indian settlement and would also reserve land for the Yankton-Sioux Tribe north of the Missouri River in current Charles Mix County. A monument was established near Greenwood, SD in honor of those who signed the Yankton Sioux Treaty of 1858.
