The lightning-caused wildfire that consumed roughly 70 structures seemed unremarkable for days. High winds changed that.

The National Park Service is pushing back against members of Congress who accused the agency of allowing the Dragon Bravo Fire to spin out of control on the Grand Canyon’s North Rim.

The fire on the North Rim of the Grand Canyon started from a lightning strike but was managed as a controlled burn until it spread.

All wood-burning and charcoal fires, such as campfires and charcoal barbecues, are prohibited. In addition, visitors and residents can only use liquid petroleum appliances like stoves, lanterns or heating devices in an empty area or one that doesn’t have flammable materials within three feet.

Two wildfires continue to burn near the Grand Canyon; the White Sage Fire has burned nearly 53,000 acres and is 4% contained. The Dragon Bravo Fire has burned about 8,500 acres.

The congressman is the latest lawmaker asking why the Dragon Bravo fire was not immediately extinguished when it was ignited by lightning on July 4.

The Grand Canyon's North Bravo Fire intensified on July 11, the day before Katy Rock Shop owner Jacob Proctor and his family arrived at the national park.
