September 17, 1804 entry by Meriwether Lewis

Having for many days past confined myself to the boat, I determined to devote this day to amuse myself on shore with my gun and view the interior of the country lying between the river and the Corvus Creek—    accordingly before sunrise I set out with six of my best hunters...found the country in every direction for about three miles intersected with deep revenes and steep irregular hills of 100 to 200 feet high; at the tops of these hills the country breakes of as usual into a fine leavel plain extending as far as the eye can reach.    from this plane I had an extensive view of the river...and creek...this senery already rich pleasing and beatiful, was still farther hightened by immence herds of Buffaloe deer Elk and Antelopes which we saw in every direction feeding on the hills and plains. I do not think I exagerate when I estimate the number of Buffaloe which could be [observed] at one view to amount to 3000.
