A wildfire burns behind an abandoned truck on Alberta Highway 63 near Fort McMurray, Alberta, Canada, on Saturday, May 7, 2016. Wildfires raging through Alberta have spread to the main oil-sands facilities north of Fort McMurray, knocking out an estimated 1 million barrels of production from Canada's energy hub. Fire officials say the out-of-control inferno may keep burning for months without significant rainfall. Photographer: Darryl Dyck/Bloomberg via Getty Images
