This photo was taken from my front yard on Saturday afternoon at about 3 pm. It is a pyro-cumulous cloud created by the fire itself. The height of this cloud is about 20,000'.
We have a really destructive fire buring out of control to the north of Los Angeles. The Station Fire has been bruning for about six days and is only about 10% contained. It doubled in size overnight and has grown to a monstrous 84,000 acres--about 75 sq. mi.--of habitat burned. They do not expect full containment until Sept. 8.
I always feel so bad for all the wildlife--so many killed and displaced. They say this area has not burned in more than 60 years, which means that the ecosystem is very well established and contains the territories of many thousands of animals, birds, and reptiles. Truly a very sad time for the critters.
I haven't been able to find out which hiking areas may have been affected, but a lovely spot below Mt. Wilson called Switzer may be in harm's way.
