A red pickup rolls into a 1,000-acre pasture of dry grassland on the Fort Belknap Indian Reservation in northern Montana. Mark Azure, director of the reservation's fish and wildlife department, is out looking for buffalo when he spots about two dozen of the furry beasts gathering around a watering hole.
The animals are "grazing, wallowing, drinking, checking us out," Azure explains. He says the tribes have been working to see these bison here for years.
"This is their home, this is where they came from," he says.
