This Sept. 19, 2011 aerial photo shows a tar sands mine facility near Fort McMurray, in Alberta, Canada. Environmentalists hoping to block a proposed underground oil pipeline that would snake 1,700 miles from Canada to the Gulf of Mexico have pinned their hopes on an unlikely ally _ the conservative state of Nebraska where opposition to Keystone XL pipeline has risen steadily since the project was proposed three years ago. Public hearings will start Sept. 27, in Lincoln on the 16-inch steel pipe that if built would carry oil extracted from tar sands in Alberta, Canada, through Montana, South Dakota, Nebraska, Kansas and Oklahoma to refineries in Texas.
