Tetoharsky, along with Twisted Hair, accompanied the expedition down the Clearwater and lower Snake Rivers, acting as river guides and interpreters. They continued down the Columbia to The Dalles, the line between Sahaptian and Chinookan speaking peoples. At that point they asked to leave. On 25 October, Clark mentions their departure:
a parting Smoke with our two faithful friends the Chiefs who accompanied us from the head of the river, (who had purchased a horse each with 2 robes and intended to return on horse back)
On the return journey, Tetoharsky met the travelers on the Travois Trail and later showed them where to cross the Snake River.
