In addition to these national forests and forest units, a parcel of land completely surrounding the Chalk Buttes mountain range in Carter County, Montana was also included:^[10]

• Chalk Buttes, Carter County, Montana 45°44′03″N 104°41′11″W / 45.73417°N 104.68639°W / 45.73417; -104.68639 (Chalk Buttes), 3,840 acres (15.5 km²) ^[11]

With these eight land units, the Sioux National Forest comprised 249,653 acres (1,010.31 km²). ^{[lower-alpha 1]}

Upon its inception in 1908, Seth Bullock, the first sheriff of Deadwood, South Dakota, was appointed supervisor of Sioux NF^[10] by President Theodore Roosevelt. (In 1900, during the McKinley administration, then-Vice President Roosevelt had appointed Bullock supervisor of the Black Hills Forest Reserve, which later became Black Hills National Forest.]

On January 13, 1920, Sioux NF was absorbed by Custer National Forest.^[1] Although the name Sioux was discontinued as a national forest designation, Custer NF created the Sioux District, which comprised the eight land units of the Sioux NF.

In 2014, Custer National Forest merged with Gallatin National Forest to form Custer Gallatin NF.^[12] Within this new entity, Custer NF’s Sioux District was replaced by the Custer Gallatin NF Sioux Ranger District,^[13] which encompasses the Chalk Buttes, Ekalaka Hills, Long Pines, North Cave Hills, South Cave Hills, East Short Pine Hills, West Short Pine Hills, and Slim Buttes land units.^[14]
