I think, the last photograph does not show the Cheyenne Wooden Leg. In his adult age ( period of time 20 - 40 ) Wooden Leg was only two times in South Dakota .
For the first time he was in South Dakota in 1883, Wooden Leg was then a member of a Northern Cheyenne band, that returned from Oklahoma to Montana. On their way back home, there was a layover in Pine Ridge.
For the second time he came to South Dakota as an army scout in late 1890, during the Ghost Dance Movement, again in or around Pine Ridge.
