We can now tell you exactly what caused black smoke to fill the Lubbock sky this morning.
The billowing smoke that could be seen for miles was caused by the burning of thousands of tires, abandoned cars, and grass.
"anytime you have a bunch of tires on fire it produces a horrific amount of smoke. With the little bit of wind we had today it's blowing right across the city. It looks big, but it's really small in nature," said Tim Smith, West Carlisle F.D. Fire Chief
Fire officials say the fire was on Highway 114 near the Lubbock and Hockley county lines.
The fire started just after 11 a.m. when someone was burning grass. The fire soon got out of control and spread.
Carlisle, Levelland, New Deal, Smyer, and Wolfforth fire departments all responded to the fire.
Crews fought the flames for more than two hours, before it was contained. No injuries were reported.
