Note 79 — Chapter XXX · RETURN FROM FORT CLARKE TO THE CANTONMENT OF LEAVENWORTH, FROM APRIL 18TH TO MAY 18TH

For the earlier adventures of Hugh Glass, see our volume xxii, p. 294, note 255. Powder River, called Red Stone by Lewis and Clark, is the most easterly of the great southern affluents of the Yellowstone. It rises in Central Wyoming, on the eastern slopes of the Big Horn Mountains and south thereof, near the sources of the Big Cheyenne and North Fork of Platte. The valley of Powder River was a favorite rendezvous of trappers, for it afforded both game and pasturage in abundance.—Ed.
