A Texas House committee confirmed on Wednesday that a decayed power pole causing power lines to fall on dry grass in the Texas Panhandle, sparked the state’s largest wildfire in history.

The committee also confirmed other poorly maintained power equipment sparked four other fires across the Panhandle earlier this year.

The Texas House Committee also found that a lack of readily available air support, ineffective communication from faulty equipment, and coordination among agencies inhibited on-the-ground efforts to contain the Smokehouse Creek fire and others that ravaged the Panhandle earlier this year.

Two people died and more than 1 million acres were seared across several counties — Hutchinson, Hemphill, Roberts, Carson, Gray and Wheeler. In the Panhandle.
