A federal judge in Great Falls Thursday night blocked the construction of the Keystone XL Pipeline until the U.S. government further studies its impact on the environment and climate.

The controversial pipeline would carry crude oil from Canada to U.S. refineries in the Gulf Coast. The 36-inch-wide Keystone XL would pass through six eastern Montana counties and near the Fort Peck Indian Reservation.
