In a book entitled, The Discovery of Yellowstone Park, written by Nathaniel P. Langford, the author gives an account of an expedition of 130 persons who started from St. Paul, June 16, 1862, for the Salmon River, as it had been widely rumored that extensive placer mines had been discovered there. The expedition was led by Captain James L. Fisk, the noted Indian fighter. Among his assistants were E. H. Burritt, Nathaniel P. Langford, and Samuel R. Bond, who acted as secretary. David E. Folsom, Robert C. Knox, Cornelius Bray, Patrick Doherty, Ard Godfrey, and Patrick Bray, were selected for guard duty. Many well-known pioneers of Montana were in this company, whose names are familiar to the writer.
After eighteen weeks of hazardous adventure, the expedition arrived, on the 23d of October, at Grasshopper Creek. The weather being too cold for them to proceed on the journey, they decided to camp in that locality for the winter. This region was then the rendezvous of the Bannack Indians; and the St. Paul expedition named the settlement Bannack.
