This chapter follows Lewis and Clark as they traveled upstream of the Missouri River. A curious change occurs on the Missouri River upstream from Fort Peck Dam and from there to Loma, near Fort Benton, Montana. The river seen at Fort Benton or on a float trip through the White Cliffs area — the wild and scenic portion of the Missouri River — appeared very different from the river upstream from Great Falls or downstream from Fort Peck Dam. Below the site of Fort Peck, the Missouri flowed, as it does today, in a wide and gently sloping valley. Above it, the river flowed through a narrow and steep valley.
