Sergeant Pryor and Pierre Dorian, a trader among the Yankton Sioux, went to make contact and invite the Sioux to a council at Calumet Bluff. It was in the Yankton camp that Pryor became the first Corps member to see a tepee. Pryor reported their camp"was handson of a Conic form Covered with Buffalow Roabs Painted different Colours..." (Clark's journal entry- Aug. 24, 1804). An authentic buffalo tepee stands in the museum, left. An interior view of the smoke hole, center. A decorated war bonnet hangs from the side of the tepee, right. The museum is located at the St. Joseph Indian School in Chamberlain, SD.
