Do you mean that the satellite misdetected fire activity?

We're talking about the imprecise satellite fire reports on caltopo, I think. AW had a good point: if you select specific satellites, it tells you the reported temperature, that one can interpret as a confidence of some sort.

I just figured out how to get flightradar24 to give you altitudes, which you can use to figure out where the tankers made their drops (the plane descends, makes the drop, and then climbs back up). On the most recent pass it dropped right around the ridge-top E of buckhorn. That makes me think it hasn't crossed over yet, but they're concerned about it.

They appear to be setting up a line on Kratka Ridge. Wonder if they bulldozed it. That'd be a shame...it's a nice ridge for a stroll from Three Points to Waterman to Kratka.

I spent a fond night on Kratka during my SMT thru. Hope it survives.

It's burning real hot on the south side of Rankin Clamshell...started flaring up there just around 5pm-ish...super bright on the arcadia2 cam (when it rotates to look NE)...

You can see that flare up very clearly on the mt wilson cam too...here's the timelapse from 3pm—6pm:

around 4:30 something catches. still see some flames on the current image around 10pm.
on the bright side, angeles nf twitter feed saying 6% containment

poking around that link hikeup posted, this camera has a direct view of the southern front of the fire— http://www.alertwildfire.org/orangecoca ... &v=81e002f
you can watch a timelapse, although maybe only for the next 12 hours or so. crazy-looking stuff though, seeing that fire line just over the foothills:

I commute through the foothill areas around Monrovia and saw the fire three times today: morning, afternoon heading home, and tonight after dark to show my lady the fire. It’s a big jagged M shape. Bigass flames roaring up that look massive. Solid view from the baseball diamond at the park in Duarte off Shamrock just north of Royal Oaks.

Looks like the good news is official for the armchair amateurs like myself. No red on the GOES. The crews worked on it all night, south and north....I have the north ending at 7 am.

I drove around Duarte, Monrovia and Arcadia at sunrise a couple hours ago. The smoke was so thick I couldn't see the mountains at all, let alone the fire, which had intensified overnight.

6:00 AM - Fire in Santa Anita Canyon seen from Mt. Wilson.

According to the latest satellite data, the north front crossed Kratka into Snowcrest, the west front is nearly into upper Devils Canyon, and the south front is on the doorsteps of Chantry Flat and Arcadia Wilderness Park. Can anyone confirm this?

Taking FLIR imagery?

ANF just released this map.

6:00 AM - Fire in Santa Anita Canyon seen from Mt. Wilson.

I think that's white horse peak in the middle of the flames in your image - fire eating its way a bit lower into the east fork santa anita - the archive images show a sudden drop in activity shortly after that image so maybe they dropped something on it.

Why does everything smell like hickory-smoked beef jerky all of a sudden?

I think I detect a hint of bear, deer and mountain lion too.

Yeah, the south I consider a de facto controlled burn...I dont count it anymore.

For the northern end, its over but the process.
There is one thing left: the start.

The super scoopers were located!

Angeles twitter account posted that the fire is "near Chantry Flat" —

Looking at the Mt. Wilson cam, it does look like it's dipped quite a bit further into Big Santa Anita:

Looking awfully close the foothills now too...
first image is looking over santa anita dam, second image towards monrovia from the south. can't tell if it's below clamshell rd yet

I made this based on recent towercam images. It shows how low the fire has reached in Santa Anita Canyon. Chantry is behind the ridge on the right around 2200' in elevation, directly across the canyon from the fire front, maybe half a mile away as the bird flies.

Not looking good for Chantry Flat or all the cabins in BSAC.

To the north, the Triplet Rocks ridge has burned and it looks like the East Twin as well. All the Mermaids below. It will probably jump the Angeles Crest soon...

What a devastating fire for my favorite mountain range.

patrick · Post by **patrick** » Sun Sep 13, 2020 12:15 pm

Looks like they're really trying to hold it at the river below Chantry:

patrick · Post by **patrick** » Sun Sep 13, 2020 4:51 pm

looks really horrifying from mt wilson right now:

i counted seven aircraft working the fire just now on fr24, all on the southern side

Post by **HikeUp** » Sun Sep 13, 2020 4:57 pm

I think Mt. Zion is burning.

2 tankers are circling. They stopped it from running in to Monrovia, now they are concentrating on Mt. Wilson before dark.

fire got to chantry flat, per forest service:
