A wildfire that blackened 24 open acres in a remote section of northern San Diego County was 100% contained as of Thursday afternoon.
The Sandia Fire had been 10% contained Tuesday night, and rose to 35% containment by Wednesday morning, then 90% by early Thursday, Cal Fire said.
Fire crews took advantage of favorable weather conditions on Wednesday and made good progress throughout the day. Firefighters remained on scene Thursday morning continuing to build on containment lines and extinguish remaining hot spots.
The blaze erupted for unknown reasons shortly before 3:30 p.m. Tuesday in the rural De Luz community, north of Fallbrook and just south of the Riverside County line.
The flames, which caused no reported structural damage or injuries, spread over steep, rugged terrain near Sandia Creek Road, for a time threatening about a dozen homes in the area of Doville Ranch Road.
The investigation is continuing.
