In 1860 the area of Montana that lies east of the Continental Divide was part of Nebraska Territory. Persons residing in this area were enumerated in the unorganized part of Nebraska Territory. The only exceptions to this were two trading posts, Fort Alexander and Fort Union, which were enumerated with unorganized Dakota. The area of Montana west of the Continental Divide was enumerated as the Bitterroot Valley and the Ponderay Mountains in Spokane County, Washington Territory.

(Helena, Mont.: Rocky Mountain Publishing Co., 1876). Yellowstone National Park was created in 1872, and all residents of the area were enumerated in the Wyoming census for 1880.
