Left on this road to CHALKY BUTTE, also known as White Butte, =6 m.=, a long high butte topped with one of the few White River limestone formations in the State. On its steep talus-covered slopes fossilized teeth and bones of prehistoric animals have been found. Outcroppings of large bones are plainly visible in the limestone cliff. The complete skull and other bones of an oreodon (small prehistoric hoofed animal) have been taken from this fossil bed. In early days of white settlement it was believed that a treasure was buried somewhere on Chalky Butte because an Indian chief often went there and returned with gold. Although he was followed, he always managed to elude his pursuers; his cache, if it existed, has never been found. According to another story, a small party of soldiers once left Fort Meade, in the Black Hills, to take the pay roll to Fort Keogh, Mont. The pay roll never reached Fort Keogh, and no trace was found of the men, unless the three revolvers marked "U.S." and several U. S. Army wagon irons with charred pieces of wood clinging to them, found about 1900 near Sunset Butte S. of here, were the remains of their luckless expedition. Whether or not there is any connection between these two stories is a matter of conjecture. AMIDON, =223.5 m.= (2,800 alt., 141 pop.), named for a U. S. district judge, Charles F. Amidon (1856-1937), was organized in 1915 and shortly thereafter was selected Slope County seat. In an enclosure near one of the filling stations in the town is an 8-ton petrified stump almost 6 ft. in diameter, which was uncovered on the county fairgrounds N. of Amidon. The town commands a good view of the surrounding country, with Chalky Butte to the SE., the angular outlines of the Badlands to the N. and W., and Black Butte (_see below_), highest point in the State, to the SW. At =225 m.= is the junction with a graded dirt road with sharp curves and abrupt hills (_unsuited for trailers_). Right on this road =2 m.=; then L. across rolling range land, gradually descending into the Badlands to the junction with a little-used trail, =11 m.=
