Panic Not

I tell you this in advance – this is not necessarily a terrible thing. It’s under control, even if it doesn’t seem that way. We’ll get through this and come out stronger and better on the other side.

You and I aren’t the experts. Don’t try this at home.

All images from the HPWREN cameras on Mount Wilson, run by UC San Diego. (I would also note that they put out time-lapse videos for each of the four cameras for every three-hour period, 24 hours a day, and the archive goes back a couple of years. There’s an interesting one on my birthday of it snowing like crazy up there. For those who don’t know how it can snow in Los Angeles County, remember this is at about 5,700 feet. Lots of things are different there. That’s why we have ski resorts just a 90 minute drive from the beach.)

Again, this national treasure is *NOT* burning to the ground tonight – but it sure looked like it if you didn’t get the memo. Just a few minutes after 19:00 local time, looking east, just beyond the line of big domes, there was a puff of smoke:

A half-hour later it was a huge blaze. What we had missed was this:

The “good window of opportunity with favorable conditions” equals cool(er) temperatures, higher humidity, light winds, and most importantly, winds that will push the flames away from the domes and back down the ridge to where it had already burned.

That “existing retardant line?” I think this picture from yesterday explains that:

So the pros saw their chance and took it!

It’s up on top of the ridge where the observatories are and looks like it’s only a few meters from some of the facilities. That’s because it was.

Then it started to die down a bit over there…

…before flaring up over here.

And now it’s all died down and is being put out.

Mount Wilson appears to have been saved from this horror. The fire is less than 20% contained and on the north side, leading into the Antelope Valley, there are more new evacuations tonight. Some of the evacuation areas on the south side around Glendale (where all of those lights are in the right center) have been lifted, but many are still in place for the eighth day. But for now, looking at the weather and the containment lines and defensive burns like tonight’s, it seems that Mount Wilson is safe.

So many thanks to the firefighters who have made this happen. In this hell of a year, we need to grab our victories where we can.

And for those who might think that I’ve slipped into a fugue state and obsessing over Mount Wilson because I can’t face what’s going on in the real world these days – go back and read the first sentence.
