In addition to the above, there were about fifteen men who acted as teamsters, laborers, cooks, or hunters. The greater portion of our outfit was obtained of the United States quartermaster, Colonel C. A. Reynolds, at Fort D. A. Russell, Wyoming Territory. Horses, mules, wagons, and all other equipments were placed on freight-cars and taken by rail to Ogden, Utah. Here our journey began." --Ferdinand Hayden in his report to Congress, 1972
