A wildfire burning in a sparsely populated region of central Oregon has become the largest fire this year and is on the verge of surpassing 100,000 acres to become a megafire.

At least 850 personnel are fighting the Burdoin Fire and some national forest lands in the Columbia River Gorge are now closed.

The Cram fire burning in central Oregon is the largest wildfire in the nation as the Pacific Northwest sees an active start to the fire season. Why it matters: Thousands of acres have already been scorched and dozens of homes destroyed.
