Mouth of the Big Sioux River

Description

The Yellow Stone reached the mouth of the Big Sioux River early on the morning of May 8. Dated this day is Bodmer's watercolor sketch of the confluence of the Big Sioux with the Missouri below present Sioux City, Iowa. Near the mouth of the Vermillion River on May 10, steamer passengers had their first glimpse of a beaver lodge. On May 11 several Indians came aboard the Yellow Stone; they disembarked the following day at the Ponca village below the mouth of the Niobrara.
