Clark recorded in his journal on November 4, 1804
A french man by Name Chabonah, who Speaks the Big Belley language visit us, he wished to hire & informed us his 2 Squars (squaws) were Snake Indians, we engau (engaged) him to go on with us and take one of his wives to interpret the Snake language
Charbonneau and Sacagawea moved into the expedition's fort . Clark called her Janey ,Sacagawea's sonJean Baptiste Charbonneau was born on February 11, 1805.The expedition left Fort Mandan in April,they headed up the Missouri River. Even with a young baby Sacagawea proved to be helpful in many ways on the trek. She found edible plants for the explorers. When a boat she was riding on capsized, she was able to save some of its cargo, including important documents and supplies. They named the Sacagawea River in her honor on May 20, 1805.The expedition had located a Shoshone tribe in August 1805, they wanted to trade for horses to cross the Rocky Mountains. Sacagawea interpreted for the expedition and discovered that the tribe's chief was her brotherCameahwait.
Lewis recorded their reunion in his journal
Shortly after Capt. Clark arrived with the Interpreter Charbono, and the Indian woman, who proved to be a sister of the Chief Cameahwait. The meeting of those people was really affecting, particularly between Sah cah-gar-we-ah and an Indian woman, who had been taken prisoner at the same time with her, and who had afterwards escaped from the Minnetares and rejoined her nation.
Clark recorded also their reunion in his journal
The Intertrepeter & Squar who were before me at Some distance danced for the joyful Sight, and She made signs to me that they were her nation
Lewis and Clark on the Lower Columbia
The Shoshone agreed to the trade for their horses, they also provided guides to lead them over the Rocky Mountains.On the trip over the mountains they had to eating tallow candles to survive. When the expedition reached the the Columbia River, Sacagawea gave Lewis and Clark her beaded belt so could trade for a fur robe they wanted to give to President Thomas Jefferson.
Clark wrote in his journal on November 20, 1805
One of the Indians had on a robe made of 2 Sea Otter Skins the fur of them were more beautifull than any fur I had ever Seen both Capt. Lewis & my Self endeavored to purchase the roab with different articles at length we precured it for a belt of blue beeds which the Squar—wife of our interpreter Shabono wore around her waist.
When they reached the Pacific Ocean they built a winter fort. On July 6 on the return trip, Clark wrote The Indian woman informed me that she had been in this plain frequently and knew it well.... She said we would discover a gap in the mountains in our directionwhich is now called Gibbons Pass.On July 13, Sacagawea told Clark to cross into the Yellowstone River basin,what is now known as Bozeman Pass. While traveling through what is now Franklin County, Washington, Clark wrote The Indian woman confirmed those people of our friendly intentions, as no woman ever accompanies a war party of Indians in this quarter,and the wife of Shabono our interpeter we find reconsiles all the Indians, as to our friendly intentions a woman with a party of men is a token of peace.

At the end of the journey, Clark wrote to Charbonneau
You have been a long time with me and conducted your Self in Such a manner as to gain my friendship, your woman who accompanied you that long dangerous and fatigueing rout to the Pacific Ocian and back diserved a greater reward for her attention and services on that rout than we had in our power to give her at the Mandans. As to your little Son (my boy Pomp) you well know my fondness of him and my anxiety to take him and raise him as my own child...If you are desposed to accept either of my offers to you and will bring down you Son your famn [femme, woman] Janey had best come along with you to take care of the boy until I get him....Wishing you and your family great success & with anxious expectations of seeing my little dancing boy Baptiest I shall remain your Friend, William Clark.
