Several years later a portion of the United States Exploring Expedition under the command of Lieutenant George F. Emmons (1838-1842) visited the Klamath Mountains. Emmons had been given instructions by Charles Wilkes to explore the headwaters of the Klamath, Sacramento, and Umpqua rivers. The assembled men had departed from Fort Vancouver to Fort Umpqua during the summer of 1841. During September and October they traveled through Shasta territories by generally following the Siskiyou Trail. On 1 October the party crossed the Klamath River. The explorers visited a Shasta village where inhabitants gave them salmon and sold several yew bows and arrows in exchange for trade goods. Inhabitants of the village demonstrated their archery skills by repeatedly shooting a button from distant. At this demonstration was an elder Shasta man who was a father-in-law to Michel Laframboise. Shortly after this peaceable dialogue and trade Emmons ordered the party to depart for Destruction river (the Upper Sacramento River) exiting Shasta lands for those of the Okwanuchu and later the Wintu.
