LITTLEFIELD, Ariz. -- A wildfire burning in a remote area of northwest Arizona has consumed nearly 23 square miles of grasslands.
The federal Bureau of Land Management says the blaze it is calling the Hidden Fire broke out Saturday after a lightning strike.
The fire on the Arizona Strip about 25 miles southeast of Mesquite, Nev., had consumed more than 15,000 acres by Sunday evening.
No structures are threatened in the remote area. The nearest building is the BLM's Pakoon fire station.
The fire is mainly burning cheatgrass within a rugged area scorched by a larger fire in 2005.
Seven fire engines, two hand crews, four single-engine air tankers and two helicopters are assigned to the fire.
