Archaeological excavations at Huff Village took place in 1938-1939, 1959, 1960, and 1999, and in all but the most recent work they focused on uncovering houses and understanding details of prehistoric architecture. The floors of 11 of the 103 or more houses at Huff Village have been completely exposed. Ten of these houses lay in a row along the riverbank, and they were excavated before the riverbank was graded to a slope to stabilize it against erosion from Lake Oahe, previously the Missouri River. Eight of the 11 excavated houses are remarkably similar in size and architectural details. House 9, although it had a typical surface depression, did not show the formal construction plan or the arrangement of posts and pit features seen in most other houses. House 12 revealed a very unusual floor plan unlike any of the other excavated structures and is interpreted as reflecting an impending change in village-wide building codes. House 2 was unique in its placement and size and probably served as a special-purpose community center of some kind.
