East side of 100s block of Capital Street in Yankton, South Dakota. Camera is looking northeast from about the intersection of Capital and Levee Streets. Two of the buildings in the photo are part of the House of Gurney Historic District, listed in the National Register of Historic Places. The leftmost (northernmost) building, at the southeast corner of Capital and Second Street, is 110 Capital. The Excelsior Flour Mill occupies most of the photo: it consists of what appear to be two or three buildings: the white rightmost (southernmost) building; the reddish building with its windows filled in with white material, just left of center; and the dark brick filler between them.
