July 19th after breakfast which was on a rosted Ribs of a Deer a little and a little Coffee I walked on Shore intending only to Keep up with the Boat, Soon after I got on Shore, Saw Some fresh elk Sign, which I was induced to prosue those animals by their track to the hills after assending and passing thro a narrow Strip of wood Land, Came Suddenly into an open and bound less Prarie, I Say bound less because I could not See the extent of the plain in any Derection, the timber appeared to be confined to the River Creeks & Small branches, this Prarie was Covered with grass about 18 Inches or 2 feat high and contained little of any thing else, except as before mentioned on the River Creeks &c, This prospect was So Sudden & entertaining that I forgot the object of my prosute and turned my attention to the Variety which presented themselves to my view after continueing on this rise for Some minits, I deturmined to make my course to a line of woods to S. E. I found in this wood a butifull Streem of running water, in prosuing it down Several others Joined it and at 3 miles fell into the river between 2 clifts, I went up & under one clift of dark rich Clay for 1/2 me. above this a Clay bank which had Sliped in here I found Sand Stone Containing Iron ore, this ore appears to be inbeded under the Clay just above the water
