Note 67 — Chapter V · [1]
Reading edition
Andrew Henry, one of the partners of the Missouri Fur Company, in the autumn of 1818 built a post on the north fork of Lewis or Snake (Saptin) River. This was maintained only until the following spring, but is renowned for being the first American trading post on Columbian waters. The site was supposedly near Egin, Idaho, and the stream has since been known as Henry’s Fork.—Ed.
