A small brush fire briefly threatened homes Friday in a back-country neighborhood in eastern San Diego County before crews were able to snuff out the flames.

The blaze off Real Way Lane in Alpine erupted for unknown reasons about 1:30 p.m., according to Cal Fire.

Ground and airborne firefighters had the spread of the flames halted within about 20 minutes, said Jon Heggie, a fire captain with the state agency.

No structural damage or injuries were reported.

The cause of the roughly half-acre fire, which burned within several hundred yards of residences, was under investigation, Heggie said.
