The area is in northeastern Liberty County, where a woman doing some work on her property discovered some wires sticking out of a hole in the ground. She called the Railroad Commission, who sent someone out to investigate.
Rex Evans with the Liberty County Sheriff's Department says officials determined the item was an old seismograph explosive left behind by a demolition company that had once used the property. There were fears the item could be unstable, so the county bomb squad was called to the scene.
Evans says a couple of homes near the site have been evacuated. There are no homes in the immediate area.
