A wildfire that has closed the North Rim of Grand Canyon National Park raged out of control over the weekend and is now the largest currently burning in the country. The Dragon Bravo fire has burned more than 133,000 acres and was only 13 percent contained as of Wednesday morning, according to a federal interagency website that tracks wildfires.

The Dragon Bravo fire has been burning for more than a month, fueled by record-low humidity that has hampered containment efforts.

The fire on the north rim of the Grand Canyon has burned more than 120,000 acres after starting a month ago. Meanwhile, dry conditions north of Los Angeles are making the containment of a fire burning through a national preserve more difficult.
