The Fort Peck Indian Reservation encompasses just over 2 million acres of rolling grasslands and prairies along the Missouri River in far northeastern Montana. Rising from the banks of the “Mighty Mo’” in the south and nearly reaching the United States–Canada border in the north, the reservation is vast, alive with undulating terrain and near constant wind. At its southern edge, one can stand on the riverbank, gaze out over the prairies, and almost see history unfolding among the waving grasses. At least, one can see the history one knows.
