The road to the southeast leads to the mouth of the Judith River, where Fort Chardon, an early fur post, was built in 1844. In 1866 Camp Cooke, the first military post in Montana, was constructed there of cottonwood logs and endured four years of isolation before soldiers were driven out by rats. In 1855 Governor Isaac Stevens signed a peace treaty giving Northern Plains tribes all lands east of Sun River and north of the Missouri. By 1887 the Indians had been pushed into smaller reservations, and cattle moved into the country north of the rivers. In 1884 T.C. Power, a Montana merchant prince, and his partner Gilman Norris established one of Montana's big cattle ranches in the area, and some original buildings remain just across the Missouri.
