Visitors to Devils Tower National Monument will spot the Tower formation from miles away. Many also notice several mound-shaped formations at a distance from the Tower. These are the Little Missouri Buttes.
Located about 3.5 miles to the northwest of the Tower, the buttes take their name from the Little Missouri River, which has its headwaters nearby. In 1892, Wyoming Senator Francis Warren sought to protect the entirety of Devils Tower and the Little Missouri Buttes by creating a forest reserve encompassing all of the formations. Although only the Tower was permanently protected, the other buttes are still linked to the Tower both visually and geologically.
