Bismarck, North Dakota
Santana Running Bear, 8, from the Cheyenne River Reservation in South Dakota, and Wanahcha "Sunflower" Rowland, 10, from the Pine Ridge Reservation in South Dakota, ride in the back of a truck, announcing a youth gathering that evening at the Sacred Rock camp.
When visitors turn off a narrow North Dakota highway and drive into the Sacred Stone camp where thousands have come to protest an oil pipeline, they thread through an arcade of flags whipping in the North Dakota wind. Each represent one of 280 Native American tribes that have flocked here in what activists are calling the largest, most diverse tribal action in at least a century, perhaps since Little Bighorn.
