Looks like Chantry Flats, Mt. Wilson Trail and other nearby trails are going to be closed for some time.
The fire started yesterday around 3:00 Pm right near the Chantry Flats rd. Several people were trapped above in the Chantry Flats area, until they were escorted down later in the day.
Once it became dark and the air drops stopped, the fire kept moving Westward, and downward, towards Sierra Madre.
Much of the city, above Grandview, is being evacuated today by LASD and other law enforcement agencies (mandatory).
So far, the fire has burned into Little Santa Anita Canyon and is moving up towards Jones Peak. NO houses lost so far.
There are (3) helicopters, a fixed-wing aircraft and lots of fire crews working on the fire today.
here are some pictures (I hope).
