August 12th – Today in Oregon History

The Lewis and Clark Expedition crosses the Continental divide at Lemhi Pass, leaving the Louisiana Territory, and entering what would become the Oregon Territory. Today it is on the Idaho-Montana border.

” after eating we continued our rout through the low bottom of the main stream along the foot of the mountains on our right the valley for 5 mes. further in a S. W. direction was from 2 to 3 miles wide the main stream now after discarding two stream on the left in this valley turns abruptly to the West through a narrow bottom betwen the mountains. the road was still plain, I therefore did not dispair of shortly finding a passage over the mountains and of taisting the waters of the great Columbia this evening. we saw an animal which we took to be of the fox kind as large or reather larger than the small wolf of the plains. it’s colours were a curious mixture of black, redis-brown and yellow. Drewyer shot at him about 130 yards and knocked him dow bet he recovered and got out of our reach. it is certainly a different animal from any that we have yet seen. we also saw several of the heath cock with a long pointed tail and an uniform dark brown colour but could not kill one of them. they are much larger than the common dunghill fowls, and in their [h]abits and manner of flying resemble the growse or prarie hen. at the distance of 4 miles further the road took us to the most distant fountain of the waters of the mighty Missouri in surch of which we have spent so many toilsome days and wristless nights. thus far I had accomplished one of those great objects on which my mind has been unalterably fixed for many years, judge then of the pleasure I felt in allying my thirst with this pure and ice cold water which issues from the base of a low mountain or hill of a gentle ascent for ½ a mile. the mountains are high on either hand leave this gap at the head of this rivulet through which the road passes. here I halted a few minutes and rested myself. two miles below McNeal had exultingly stood with a foot on each side of this little rivulet and thanked his god that he had lived to bestride the mighty & heretofore deemed endless Missouri. after refreshing ourselves we proceeded on to the top of the dividing ridge from which I discovered immence ranges of high mountains still to the West of us with their tops partially covered with snow. I now decended the mountain about ¾ of a mile which I found much steeper than on the opposite side, to a handsome bold running Creek of cold Clear water. here I first tasted the water of the great Columbia river. ”
