The Cross Ranch Archeological District near Hensler, North Dakota is a historic district that was listed on the National Register of Historic Places (NRHP) in 1985. The listing included 149 contributing sites.
Among the sites in the district, Bagnell (32OL16) was seemingly occupied during the late sixteenth and early seventeenth centuries AD. Houses excavated at the site have produced significant evidence of the architectural practices of the residents: posthole patterns and other features suggest that the houses represent a transition to the earthlodges found among area tribes during the historic period.
