Go to the intersection of West 2nd Street and Riverside Drive to pay tribute to the first white settler in the Yankton area. Pierre Dorian lived among the Yankton Sioux at the time that Lewis & Clark passed through in 1804.

Lewis & Clark convinced Dorian to accompany them on their expedition and to serve as an Indian interpreter. Dorian later returned to the Yankton area. His grave was located by a local historian and a memorial marker dedicated in 2002.
