Documents a ceremony in 2006 to honor Big Medicine, a white buffalo born on the National Bison Range in 1933. White buffalo are sacred to many Native American tribes. The ceremony, carried out on the Flathead Indian Reservation in western Montana, involved the participation of 700 local school children, who formed the shape of a giant white bison. The Big Medicine art performance was designed and carried out by Daniel Dancer. Dancer has done dozens of these live-art performances around the country, which he calls “Art of the Sky”. Once the image is in place, Dancer takes photos of the art from a “cherry-picker” crane, preserving the image for posterity. BIG MEDICINE is a co-production of High Plains Films and the Independent Television Service (ITVS).
