South of Minot the route is over level drift prairie, gradually rising to a ridge of hills at =85 m.= This is the HEIGHT OF LAND, the northern rim of the Plateau du Missouri, which is the watershed between the Gulf of Mexico and Hudson Bay, and also marks the farthest advance of the last glacier. In addition to its geologic interest, the elevation commands a view northward almost to the Canadian border. MAX, =96 m.= (2,100 alt., 500 pop.), a Russo-German community, was named for the eldest son of an early settler. At =109 m.= is the junction with ND 37 (_see Side Tour 3A_). COLEHARBOR, =118 m.= (1,900 alt., 153 pop.), derives its name from the unsuccessful attempt to make this a river shipping point for lignite coal, which is mined in this vicinity. UNDERWOOD, =126 m.= (2,020 alt., 488 pop.), is the center of a large diversified farming area. The railway conductor for whom it was named, in appreciation of the honor, donated a bell to the school. The town has a circulating library, begun by a 72-year-old man, Edward Erickson, who bound newspaper and magazine stories into books. With these he began his collection, and by the time of his death in 1932 his work, together with donations, had resulted in a library of 8,000 volumes, most of them now available to the public at the office of the Underwood _News_. WASHBURN, =143 m.= (1,731 alt., 753 pop.), McLean County seat, on the eastern bank of the Missouri River, is named for Gen. W. D. Washburn of Minneapolis, who was instrumental in its development. One of the earliest Missouri boat landings was established at Washburn, and the town was an important trading post in pioneer days. Where the waterworks stand NW. of the city is the SITE OF A SIOUX-ARIKARA BATTLE fought on May 22, 1869; it resulted in the death of Swift Runner, young Ree chieftain. On E. Main St. stands the LOG CABIN OF JOSEPH HENRY TAYLOR (_open by arrangement_; _inquire at_ Leader _office_), trapper, hunter, and author, who built the house near Painted Woods (_see Side Tour 3B_) in the early 1870's. He established a woodyard there, and also became the first postmaster of the settlement; the post office was a hole cut in the trunk of an oak tree. Taylor printed his books in his own shop, writing the stories as he set the type by hand. His books include _Frontier and Indian Lives_ and _Kaleidoscopic Lives_, both reflecting the somewhat florid literary style of the time, but nevertheless giving a colorful and engrossing picture of the frontier of his day.
