"The Grass Dancer" often describes a Yuwipi ceremony where tribe members gather together to call on the spirits for answers. An example of this ceremony happens in chapter 3 when Archie Iron Necklace has a dream about a medicine hole. During the Yuwipi ceremony, the spirits of Sioux ancestors guide the tribe members on a vision where Archie Iron Necklace, Herod Small War, Frank Pipe, and Harley Wind Soldier appear as young Sioux Indians riding their horses on the plain in the year 1877. On this day, one year after the Custer battle, four young warriors were trapped in the valley by white soldiers out for revenge. They prevented the warriors from escaping the valley, forcing their horses to die of starvation. When the soldiers discovered the corpses of the horses, the young warriors seemed to have vanished. The Yuwipi vision revealed how the four warriors managed to escape. The earth opened a hole and the four men were able to escape. (Power 85).
