Note 23 — Chapter V · [1]

This is Athabasca Pass, first discovered by David Thompson in 1811—see Elliott Coues, Henry-Thompson Journals (New York, 1897), ii, pp. 668, 669. Mount Hooker lay south of the pass, and Mount Brown to the north; the former is about 10,500 feet above sea level (once supposed to be more than 15,000 feet). For a description of the passage of this gap see Franchère’s Narrative in our volume vi, pp. 352-357.—Ed.
