Chief Arvol Looking Horse of the Cheyenne River Reservation in South Dakota, prepares to escort walkers on the ceremonial Dakota Wokiksuye Walk to Minnesota on Friday, August 17, 2012. This year marks the 150th anniversary of the U.S.-Dakota War of 1862, a forgotten and overlooked story of conflict between Dakota Indians and European White Settlers in nineteenth century Minnesota. The war resulted in the largest mass execution in U.S. history, and the exile of the Dakota people from the state of Minnesota. Chief Arvol Looking Horse is the 19th generation Keeper of the Sacred White Buffalo Calf Pipe, the holiest of all worship symbols in Dakota culture.
