Clark: April 15, 1805

15th of April Monday 1805 Set out at an early hour, Captn Lewis walked on
Shore and Killed a goose, passed a Island in a bend to the L. S. the wind
hard from the S. E. after brackfast I walked on Shore and assended to the
high Countrey on the S. S. and off from the Missouri about three miles the
countrey is butifull open fertile plain the dreans take theer rise near
the Clifts of the river and run from the river in a N E derection as far
as I could See, this is the part of the River which Mouse river the waters
of Lake Winnipec approaches within a fiew miles of Missouri, and I believe
those dreans lead into that river. we passed a creek about 20 yds. wide on
the S. S. the bottoms of this Creek is extensive & fertile, the water
of this as also, all the Streams which head a fiew miles in the hills
discharge water which is black & unfit for use (and can Safely Say
that I have not Seen one drop of water fit for use above fort Mandan
except Knife and the little Missouris Rivers and the Missouri, the other
Streams being So much impregnated with mineral as to be verry disagreeble
in its present State.) I saw the remains of Several Camps of ossinniboins,
near one of those camps & at no great distance from the mouth of the
aforesid Creek, in a hollow, I saw a large Strong pen made for the purpose
of Catching the antelope, with wings projecting from it widining from the
pen

Saw Several gangs of Buffalow and Some elk at a distance, a black bear
Seen from the Perogues to daypassed a rock in the Middle of the
river, Some Smaller rocks from that to the L. Shore, the dog that came to
us yesterday morning continues to follow us, we camped on a Sand point to
the L. S.
