Note 63 — Chapter XVIII · VOYAGE FROM MUSCLESHELL RIVER TO FORT MC KENZIE, FROM JULY 28TH TO AUGUST 9TH
Hannibal Evans Lloyd translation
The extensive collection of all kinds of rock in this remarkable sand-stone valley, was unfortunately lost in the fire on board the Company's steam-boat in the year 1834, and I am, consequently, unable to determine more particularly the kind of the above-mentioned rock, standing out in narrow perpendicular walls. Lewis and Clark call it a conglomerate; but this expression seems to me not to be well chosen.—Maximilian.
