Two oil tank trailers full of tar burned Wednesday afternoon, sending thick, black smoke into the air.
The vehicles were found near Sutters Landing Park, and prompted a quick response from firefighters.
Investigators say the cause of the fire is not immediately known.
No one was hurt, and no structures were damaged.
