Note 113 — Chapter XX · STAY AT FORT MC KENZIE, FROM AUGUST 9TH TO SEPTEMBER 14TH

Snow River, as named by Lewis and Clark, is a southern affluent of the Missouri not far above its junction with Maria's. The present name of this stream is Shonkin Creek, rising in Highwood Mountains, and flowing nearly north, disemboguing just below the site of Fort Benton, for many years the head of navigation on the Missouri, and the most important post of the upper country.—Ed.
