Granite Falls: Yellow Medicine and the River That Named a War

Granite Falls sits on the Minnesota River where ancient bedrock breaks the surface in outcrops that give the town its name. The county around it is Yellow Medicine County, named for a Dakota word for a plant whose yellow root the Lakota and Dakota peoples used medicinally. That plant, and the river that bears its name, appear throughout the history of one of the most consequential conflicts in Minnesota history.

In eighteen sixty-two, the Upper Sioux Agency a few miles south of Granite Falls was at the center of the U.S.-Dakota War.

Wahpetonwan leader Mazomani, also called Walking Iron, was killed at the Battle of Wood Lake in September of that year, and his grave lies at the Upper Sioux Agency site south of the town. The village itself was incorporated in eighteen seventy-nine, after the Hastings and Dakota Railroad arrived in eighteen seventy-eight and opened the valley to homesteaders. Granite Falls is the county seat and a market town, and it carries a name that echoes the deep Indigenous geography of the Minnesota River valley.
