Arizona officials are pressing for an investigation into the National Park Service's handling of the Dragon Bravo Fire, which spread after being managed as a controlled burn.

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

As of Monday, the Dragon Bravo fire on the North Rim had consumed more than 5,700 acres and was not contained, according to the U.S. Forest Service.

Fire activity on the North Rim of the Grand Canyon has forced the closure of several trails and campgrounds. Meanwhile, life goes on at the South Rim where tourists endured a smokey visit Monday.

Eight candidates will go before southern Arizona voters at the ballot box Tuesday in special congressional primaries to replace longtime Democratic U.S. Rep. Raúl Grijalva.

Crews are currently battling the lightning-caused fire, which has burned over 19,000 acres of land near Fredonia.
