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.

The Cram Fire exploded to 28,000 acres on July 15, shut down Highway 97 north of Madras and has degraded air quality in central Oregon.

The Cram fire, off of mile post 76 on Highway 97 near Willowdale and northeast of Pony Butte Road, has burned 20,000 acres and is 0% contained, according to the State of Oregon Fires and Hotspots Dashboard. There have been no reported injuries.
