CNN -  A lightning-sparked wildfire raging in eastern Oregon has scorched nearly 270,000 acres, making it the largest active wildfire in the US. The Durkee Fire, which has already burned an area larger than the entire city of Indianapolis, started over a week ago near the Oregon-Idaho state line and was still 0% contained as of early today. The extreme heat beating down on the West and other parts of the US this summer, along with high winds, could be a recipe for danger leading into the wildfire season, firefighters have warned. Meanwhile, wildfires have forced a town and a major national park in Canada's Alberta province to be evacuated. Several buildings have been burned by one of two raging wildfires menacing the town of Jasper in the Canadian Rockies' largest national park, authorities said today.
