The Joseph N. Nicollet Tower & Interpretive Center
See three states from atop the 75-foot Nicollet Tower, an observation tower with three floors that provides a breathtaking view of the great valley carved by the glacier some 40,000 years ago. The Interpretive Center next to the tower provides a 12-minute film "Dakota Encounters" about French mapmaker Joseph N. Nicollet's 1830's mapping of the area. Nicollet's map and original artwork by John Wilson are also on display. Located 3.5 miles west of Sisseton, the Interpretive Center is open mid-May through mid-October, 10 a.m. - 5 p.m., Monday through Friday, and 1 - 4 p.m. on Sunday.
