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

COCONINO COUNTY, Ariz. — Stage 2 fire restrictions will go into effect July 17 for Grand Canyon National Park due to the high threat of wildfire danger in the region. The U.S. Department of Interior said the restrictions will be applied to the South Rim and all other areas of the park.

A group of bipartisan lawmakers and officials have called for an investigation into how the Dragon Bravo Fire was able to grow and destroy dozens of structures, including the historic Grand Canyon Lodge.

Abnormally dry, hot conditions near the Grand Canyon's North Rim allowed the Dragon Bravo Fire to grow rapidly.

Gov. Katie Hobbs questioned why the U.S. government decided to manage the Dragon Bravo fire, which started with a lightning strike, as a “controlled burn” during the height of the summer.

The Dragon Bravo Fire and the White Sage Fire have now burned more than 90 square miles combined, along with dozens of structures such as the park's Historic Lodge.

The fast-moving fire destroyed a historic lodge and dozens of other structures in the Grand Canyon National Park.

A combination of high winds, dry air and above average temperatures caused a wildfire in the Grand Canyon to rapidly expand and cause major damage.
