South of Deapolis is the SITE OF FORT CLARK TRADING POST (R), for which the present village of FORT CLARK (1,726 alt., 46 pop.), downstream 1.5 m., is named. The post, a well stockaded fort 132 x 147 ft., was built in 1829 by James Kipp for the American Fur Co. and named for William Clark of the Lewis and Clark expedition. Because of its flourishing trade with the Mandans it was for several years second only to Fort Union in Missouri importance, but it was closed during the smallpox epidemic of 1837, and a few years later was abandoned by the company. The Arikara Indians reoccupied the site in the 1850's in their migration up the Missouri. Today there are slight excavations and scars marking the outline of the fort stockade walls, and traces of the Indian habitation.
Scorched Village, according to Hidatsa legend, had its locale near the present city of WASHBURN (L) (see Tour 3), but the Indians say that the site of the legendary village has been swallowed by the ever-shifting channel of the river.
The river passes WILDWOOD LAKE and the PAINTED WOODS (L) (see Side Tour 3B), and the town (R) of SANGER (1,712 alt., 70 pop.), named for its first settlers, C. H. and George Sanger. (Camp can be made in vicinity of town; L. bank more accessible.)
The route passes (R) the post office of PRICE (1,700 alt., 10 pop.), named for William Price, the first homesteader in the vicinity. Price is on the northern slopes of the flat-topped formations known as SQUARE BUTTES (see Side Tour 3B). Below these bold buttes is (L) DOUBLE DITCH INDIAN VILLAGE STATE PARK (see Side Tour 3B), and a short distance below that the route passes (R) the mouth of SQUARE BUTTE CREEK (see Side Tour 8D).
The resting place of the last physical traces of steamboating on the upper Missouri, ROCK HAVEN (R), is passed almost in sight of the black steel link of railroad bridge spanning the river near Bismarck. The advent of the railroad spelled the decline of river traffic, but before its coming Rock Haven was a river drydock and boat yard, and today three old craft which have seen sporadic service in the last decade are resting on large skids, drawn up from the waters once churned by their paddle wheels.
On the high bluffs across the river below Rock Haven are the reconstructed earth lodges of the LOOKING VILLAGE (L) of the Mandans, below which is the mouth (L) of BURNT CREEK (see Side Tour 3B).
Termination of the 350 m. voyage is made at Bismarck at a boat landing (L) reached just after passing under the N. P. Ry. Bridge. Downstream from the landing is the LIBERTY MEMORIAL BRIDGE over which passes US 10 (see Tour 8).
