Missouri Buttes or Little Missouri Buttes are located in Crook County in northeast Wyoming on the northwest flank of the Black Hills Uplift. The buttes are northwest (N60°W) of Devils Tower between the Little Missouri and the Belle Fourche rivers.[3]
The Missouri Buttes consist of four separate summits which arise from an eroded mesa platform, the Butte Divide, which has an elevation of . The butte peaks form a rough rectangle 0.5 x 0.65 mi. in size. The northwest butte is the highest with a summit at 5374feet. The northeast butte has an elevation of, the southwest butte has an elevation of and the southeast butte has an elevation of . A small lake, the Missouri Buttes Lake, lies west of the buttes.[4]
As with Devils Tower, the buttes are composed of igneous intrusive phonolite which exhibits columnar jointing. The rocks of the buttes have been interpreted to be part of a laccolith, a magmatic stock or volcano conduits that became exposed at the surface after overlying rocks were eroded.[5]
The Missouri Buttes are located on private land with no public access.[6] [7]
