After callers reported smoke in the area, crews soon discovered a trailer that was well-involved in fire that had spread to neighboring brush, but that had only burned less than a half-acre, officials said.
Aircraft were not immediately available to help douse the blaze, but firefighters on the ground were able to contain the blaze before air support was needed, officials said.
"We're looking really good on that," said county fire Capt. Sam Padilla.
There were more than a dozen aircraft at one point fighting the Colby fire, which burned more than 1,700 acres in a matter of hours Thursday morning.
