This February 2004 article in Indian Country Today discusses a lawsuit over mining pollution at the Zortman-Landusky mine complex on the Fort Belknap Indian Reservation. The Assiniboine and Gros Ventre tribes allege that pollution from mine tailings and open-pit excavation in the Little Rocky Mountains continues to pollute streams and groundwater, the tribes say, and the contamination is impacting the adjacent reservation and its residents. They also argue that the quantity of water flowing from the mine areas has been diminished.
