On a swelteringly hot day, firefighters knocked down a series of spot fires that broke out along State Route 67 in Poway on Friday afternoon.
The spot fires popped up at about 12:45 p.m. in the area of SR-67 and Iron Mountain Road, fire officials said.
SR-67 between Poway and Ramona was shut down for hours as crews battled the blaze. The roadway was fully reopened to traffic by 5 p.m.
A helicopter made several drops as well as an air tanker that made three drops of fire retardant.
No one was injured.
Prison crews started mopping up the fire just before 2 p.m., as temperatures crested from the 90s to around 100 degrees in the area.
