San Leon - An object falling from the sky could be to blame for a Saturday grass fire.

"When the call came in to the dispatcher, the person said that something fell from the sky and started the fire," Jeff Pittman, chief of the San Leon Fire Department, said.

The chief said an investigation will be conducted to determine the cause of the blaze at 18th Street and Broadway.

"It could be awhile before we figure out what happened," he said. "It could be (today) because of the lighting."

The call came in at 5:36 p.m. Saturday and the fire was under control by 7 p.m.

Along with San Leon, firefighters from Texas City, Dickinson, League City and Kemah responded to the call.

Galveston County sheriff's deputies and Galveston Area Emergency Medical Services personnel also were on the scene.

Pittman said about 60 acres of grass and brush burned.

After the fire was out, firefighters conducted a grid patrol using metal detectors to determine if something did fall from the sky, according assistant fire chief Scott Lyons.

"There was no property damage," he said. "It was an unimproved field. There were no injuries, either, just a lot of tired firemen."
