Firefighters are mopping up after a brush fire that threatened homes near San Marcos Sunday.
What's being called the Rocky Fire started around 2:30 p.m. and started spreading quickly in Elfin Forest, a neighborhood that was evacuated during the Cocos Fire last month. The fire sparked in the area of Elfin Oaks Road and Rocky Road near Painted Mountain.
The fire burned about four acres before crews had it fully contained two hours later later, according to fire officials.
Officials said three structures were threatened as the flames moved uphill toward homes. Several people were evacuated.
Crews from Cal Fire and the San Marcos Fire Department responded with a dozen trucks, two planes and three helicopters.
The cause of the wildfire is under investigation.
