Sunday 27th July 1806
I marked my name with red paint on a Cotton tree near my Camp, and Set out at an early hour and proceeded on very well the river is much wider from 4 to 600 yards much divided by Islands and Sand bars, passed a large dry Creek at 15 miles and halted at the enterance of River 50 yards wide on the Lard Side I call R. Labeech killed 4 Buffalow and Saved as much of their flesh as we could Carry took brackfast. The Buffalow and Elk is estonishingly noumerous on the banks of the river on each Side, particularly the Elk which lay on almost every point in large gang and are So jintle that we frequently pass within 20 or 30 paces of them without their being the least alarmd. the buffalow are Generally at a greater distance from the river, and keep a continueing bellowing in every direction, much more beaver Sign than above the bighorn. I Saw Several of those animals on the bank to day. the antilopes are Scerce as also the bighorns and the deer by no means So plenty as they were near the Rocky mountains. when we pass the Big horn I take my leave of the view of the tremendious chain of Rocky Mountains white with Snow in view of which I have been Since the 1st of May last.
about Sunset I Shot a very large fat buck elk from the Canoe near which I encamped, and was near being bit by a rattle Snake. Shields killed a Deer & a antilope to day for the Skins which the party is in want of for Clothes. this river below the big horn river resembles the Missouri in almost every perticular except that it's islands are more noumerous & Current more rapid, it's banks are generally low and falling in the bottoms on the Stard. Side low and exteneive and Covered with timber near the river such as Cotton wood willow of the different Species rose bushes and Grapevines together with the red berry or Buffalow Grees bushes & a species of shoemake with dark brown back of those bottoms the Country rises gradually to about 100 feet and has Some pine. back is leavel plains. on the Lard Side the river runs under the clifts and Bluffs of high which is from 70 to 150 feet in hight and near the river is Some Scattering low pine back the plains become leavel and extencive. the Clifts are Composed of a light gritty Stone which is not very hard. and the round stone which is mixed with the Sand and formes bars is much Smaller than they appeared from above the bighorn, and may here be termed Gravel. the Colour of the water is a yellowish white and less muddy than the Missouri below the mouth of this river.
