Cannon Ball, North Dakota—Protesters celebrate on December 4 after hearing that the Obama administration had halted work on the Dakota Access oil pipeline. Native Americans and environmentalists have camped out in teepees and tents since July in an effort to block construction, arguing that a breach would contaminate drinking water for the Standing Rock Sioux’s reservation. While the Army Corps of Engineers has refused to grant the pipeline company permission to tunnel under a reservoir on the Missouri River, the administration of President-elect Donald Trump supports the project and could reverse the corps’ decision.Launch Slideshow 4 PHOTOS
