The properties up there are between 1 acre and 5 acres. Lots of scrub and dirt, not many trees. What's heartbreaking right now is that so many people have horses and other livestock they weren't able to evacuate as it's moving so fast.
There are many, many, volunteers with livestock trailers waiting to be allowed back up there to evacuate the large animals. If you've been watching the news footage, I'm sure you've seen that people really do pull together anytime something like this happens. The Red Cross are quick to get into action, animal rescues and just ordinary neighbors are always quick to respond to help in any way they can.
I was here for the 2007 fires and we offered up our home to a friend's extended family burned out of Santa Clarita. There were no hotel rooms to be had in SoCal there were so many people evacuated.
Just want to add one more thing. This fire is burning scrub. The fires near me burned out the mountainside scrub, yes, but also more suburban areas. There is nothing scarier - to me - than seeing a eucalyptus or a palm tree catch fire! They go up like torches, and if there is wind, one spark can go up to 1/2 mile and start a whole new fire, just from one ember.
Fire in SoCal scares me much, much, more than a quake TBH.
