Clark: May 9, 1805

May 9th Thursday 1805 a fine Day wind from the East we proceeded on verry
well the Countrey much the appearance which it had yesterday the bottom
& high land rich black earth, Timber not so abondant as below, we
passed the mouth of a river (or the appearance of a river) on the Lard.
Side the bend of which as far as we went up it or could See from a high
hill is as large as that of the Missouri at this place which is near half
a mile this river did not Contain one drop of running water, about a mile
below this river a large Creeke joins the river L. S. which is also Dry-
Those dry Streams which are also verry wide, I think is the Conveyance of
the melted Snow, & heavy rains which is Probable fall in from the high
mountanious Countrey which is Said to be between this river & the
Yellow Stone riverI walked on Shore the fore part of this day,
& observed Great quantities of the Shining Stone which we view as
quarts, I killed 2 Bucks & a Buffalow, Capt Lewis also killed one
which verry good meat, I saw emunerable herds of buffalow, & goats to
day in every derectionThe Missouri keeps its width which is nearly
as wide as near its mouth, great number of Sand bars, the water not So
muddy & Sand finer & in Smaller perpotion. Capt. Lewis killed 4
pleaver different from any I have ever before Seen, larger & have
white breast & the underfeathers of the wings are white &c.
