PHOENIX — Arizona State Forestry said fire crews were able to stop the forward progression of a brush fire that sparked Tuesday afternoon in northwest Phoenix, near Glendale.
The second-alarm brush fire, later named the "Ultra Fire," was primarily burning near 43rd Avenue and Pinnacle Peak Road, near The 500 Golf Club and Adobe Mountain Speedway racetrack.
It was estimated to be between 30-45 acres, according to various officials.

While the official cause of the fire remains under investigation, David J. Ramirez II, public information officer for the Phoenix Fire Department, said crews are looking into whether a spark from a worker's welding torch may have caused the fire.
In an email, Ramirez said the fire began in dry grass and was further fueled by "dry brush and erratic winds."
Several agencies responded to the fire, including the Phoenix Fire Department, Peoria Fire-Medical, Glendale Fire Department, and Daisy Mountain Fire Department.
No structures were burned in the fire.
