Sacagawea recognizes a landmark in her native lands: " the Indian woman recognized the point of a high plain to our right which she informed us was not very distant from the summer retreat of her nation on a river beyond the mountains which runs west. This hill she says her nation calls the beaver’s head*."

 Lewis continues to proceed with Drouillard , Shields and McNeal in search of Sacagawea’s people. Their continuous march links them into an open plain where they discover an Indian on horseback. Captain Lewis writes: " with my eye glass I discovered from his dress that he was of a different nation from any that we had yet seen, and was satisfyed of his being a Sosone. I was overjoyed at the sight of this stranger… I made him the signal of friendship known to the Indians of the Rocky mountains… I now called in as loud a voice as I could command tab-ba-bone, which signifyes whiteman. I got nearer than about 100 paces when he suddonly turned his horse about, gave him the whip leaped the creek and disapeared in the willow brush in an instant and with him vanished all my hopes of obtaining horses for the preasent."

After searching for over an hour Drouillard returns to camp and Lewis orders a continued search around the base of the mountains. After crossing the Continental Divide by way of Lemhi Pass they encamp ( Lewis, Drouillard, Shields, and McNeal) for the evening.

I passify them."

They complete their mission and finally make friendly contact with Sacagawea’s nation.  Lewis writes: " … embraced me very affectionetly in their way which is by puting their left arm over your shoulder clasping your back, while they apply their left cheek to yours and frequently vociforate the word ah-hi-e, ah-hi-e that is, I am much pleased, I am much rejoiced. bothe parties now advanced and we wer all carresed and besmeared with their grease and paint till I was heartily tired of the national hug.
