In 1895, the Blackfeet Nation sold what is now Glacier National Park to the U.S. Government for mineral exploration. They were confined to the territory east of the park in a reservation that was gradually reduced to its present size of about one and a half million acres. The area has produced considerable oil and gas, which provides the tribe with much of its income. The two major towns are Browning and Cut Bank. The latter is on the edge of the reservation and is not a thoroughly Indian community.
