It is funny, the People at the Blanton Museum identified the (clearly) native tripod as a Camera tripod.
The Studies of Indian Chiefs is interesting. BTW: There are 3 men an one woman. I wonder if the "chief" Margo is maybe Marie Bordeaux. Bierstadt (a member of the Frederic Lander Expedition) was in Laramie about June 1859. As far as I know lived James Bordeaux with his wife Marie from about 1841 at the later Fort Laramie.
I know we discussed it before, but it would be very interesting to find more of the Bierstadt photographs.
Oh, I just saw what Kingsley wrote about the woman :"The wife of Antoine Reynal was (according to Francis Parkman) called Margot." So, maybe we have her already identified.
My optimum date for this photograph is 1853: (left to right) Horses Feared (1804-1889)(49), Jules Shangrau (1825-?)(28), No Neck (1835-1901)(18), Smoke (1774-1864)(79), Cloud Horse (1845-?)(8), Names Her (1846-?)(7), Julian Louis Shangrau (1848-1899)(5), John Shangrau (1850-1926)(3), Wiyela (1822-?)(31), Yellow Hair (1800-?)(53), Bears Foot (1852-?)(1), and Brown Eyes (1810-?)(43).
This was taken on the 1859 Lander expedition; here is the Bietstadt catalogue for 1860:
