The Crooks Fire began at 10 a.m. local time on Monday, with resources from Prescott National Forest responding, according to the Arizona Emergency Information Network.
The fire is burning through brush, ponderosa pine and mixed conifer, and has scorched around 500 acres.
"This is in an area where we have heavy fuels. It is obviously very dry and very windy. So, there was some growth on that fire today," U. S. Forest spokeswoman Debbie Maneely told ABC 15.
According to InciWeb and AZEIN, the fire remained 0% contained, even as crews – including aircraft – have been working in rugged terrain to begin to suppress the fire.
According to Fox 10 in Phoenix, 200 firefighting personnel are working to put out the fire.
Several roads were closed and smoke was said to be visible from multiple locations, including Chino Valley, Mayer and Prescott Valley.
The cause of the fire is currently under investigation.
