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 day- passed 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.
