Note 13 — THE MISSOURI RIVER JOURNALS 1843 (Continued)

"It rises to the west of the Black Mts., across the northern extremity of which it finds a narrow, rapid passage along high perpendicular banks, then seeks the Missouri in a northeasterly direction, through a broken country with highlands bare of timber, and the low grounds particularly supplied with cottonwood, elm, small ash, box, alder, and an undergrowth of willow, red-wood, red-berry, and choke-cherry.... It enters the Missouri with a bold current, and is 134 yards wide, but its greatest depth is two feet and a half, which, joined to its rapidity and its sand-bars, makes the navigation difficult except for canoes." ("Lewis and Clark," ed. 1893, pp. 267, 268.)

"We came to a green spot at the mouth of the Little Missouri, which is reckoned to be 1670 miles from the mouth of the great Missouri. The chain of blue hills, with the same singular forms as we had seen before, appeared on the other side of this river." ("Travels in North America," Prince of Wied, p. 182.)
