Tuesday, August 29, 1871, from Albert Peale's journal: "This morning we packed the wagons and started for Fort Ellis. Just before we left we went up to the Ranche and took a farewell drink of milk. The Doctor, Mr. Schonborn, Jim, Charlie, Elliott, Negley, Dawes, Jackson, and Dixon went around to the [Crow] Mission with the two ambulances. The remainder of us came by the way we came up." 
"The second day brought them into the broad, radiant expanse of Paradise Valley, and they rode as far as the Bottlers' ranch, across the river from the Emigrant mines. All of the diarists struggled to convey the majesty of the country, the meandering river backed by the unbroken, snowcapped wall of the Absarokas, with lightning and hailstorms dancing over Emigrant Peak, broken by sudden flashes of sunlight that illuminated every crevice, gully, and sparkling stream. Hedges likened the silhouette of one mountain to a crouching bear, another to a sphinx. Hauser was lost for words; the best he could manage was 'cenery superb.'" 
"After the exploring team left base camp at Bottler's ranch, Hayden split it into even smaller groups that worked independently and often widely separated from each other."
