False-color long-wave IR images from today’s Sentinel pass at 12pm. With frequent IR flights, these aren’t really useful for perimeter updates, but they do provide a qualitative view unburned areas and fire activity: CalTopo - Backcountry Mapping Evolved.

For import into CalTopo, Google Earth, etc. Can’t vouch for how accurate they keep the data vs what’s really on the ground.
Completed Dozer Line:
Completed All Type Of Line:
Planned Dozer And Hand Line:
Latest IR from 11 this morning show relatively little increase in acreage from prev. If I am intepreting it correct 
they have a good amount of some type of line in on the north side as there shows no spread in more than 2/3 (swag) of the line. Most of the increase is on the east and wrapping around on the south in SLT and in the Kirkwood area. And again, those look to be relatively small.
Also looked like the pockets SE of White Hall and SE of Kyburz burned out.
Curious if anyone who has eyes on it could describe what they’re seeing in SLT, cameras are too smoky.

Edit: Red does not mean cold/no heat! Most of the fire, including the west side still has heat in it.
From IR last night. Note that in these images yellow signifies high heat, not progression. The majority of the fire still shows moderate heat or scattered heat. I eliminated those for clarity.
West side
Above 50
Echo Lake basin looking south
Tahoe basin looking south
Tahoe basin looking north
Kirkwood looking north
Silver Lake area looking north
Progression from yesterday. Green shows increase in acreage. You’ll notice that comparing these to the previous maps above, even though the fire didn’t increase much, there is still a lot of heat (FFs like to call “potential” inside the lines)
Progression from 24 hours ago (white lines). Very Little spread but still heat throughout.
Note: I’m the last three posts on this thread. I’ll need an intervening post in order to continue.
Looking south over the head
Looking south over Echo Lakes Basin
Looking north over 50 into Desolation Wilderness
The west end. Any of those red dots have potential to cause an issue.
Looking north over Kirkwood. Looks like a unplanned finger went south near Tragedy Springs. “Potential”
The 12 hour loop on the Hawkins camera shows a lot of active fire throughout the night. Tumbleweed your maps have been very helpful and appreciated. Intervening Post.
Some of this morning’s intel, still a large number of outstanding resource needs but good to see as much black line on the map as there is, considering the resources on hand.
Per ONCC News & Notes this AM:
CA-ENF Caldor Fire: 214,107 acres brush and timber, 37% contained. Active fire behavior overnight with short-range spotting, smoldering and torching observed. Evacuation Orders and Warnings remain in effect. Many schools in El Dorado County are either evacuated or cancelled. Substantial damage to utility infrastructure reported. Repopulation occurring where safely possible with multiple communities threatened.

Briefings by both Zone Operations Chiefs sounded very confident that containment numbers would be growing significantly over the next 48 hours.
North side of the fire near Walker Lake is lined and plumbed, head fire is lined as is the area south of SLT. Caples Lake area looking much better.
I’ll won’t be updating the west side as it is essentially all black lined.
I’ve removed all the scattered/isolated heat visuals for clarity.
Looking over 50/Kyburz, still some heat
Overlooking Sierra at Tahoe, Looking north
Echo Lake Basin looking south, a lot of work being done in this area
Tahoe basin looking south. Head still is hot but it looks like they are really putting in the effort mopping up here.
However still some heat on the south side of the east zone. Looking north
The same on the south side of the upper east finger. Looking northwest
Lower east finger, hot, minimal spread, some spots. Looking northwest
A little got across 88 on the southern flank. Looking north

Latest VIIRS along with some of today’s data package:
Red dots = Detection last 24 hours.
Dark Orange dots = Detection Last 48 hours.
Light Orange dots = Detection Last 72 hours.
Cyan = Fire Perimeter.
Dark Blue lines = Completed All Types Of Line.
Purple lines = Planned All Types Of Line.
Please continue with the west side. There’s still heat showing up and residents evacuated…and pissed. One of your maps would be fabulous to share where there’s still heat. Thanks!!
Here’s an overview of the fire including all heat signature from the IR run. It should be noted that isolated heat sources can be rather large. Not all heat sources are detected by the IR flights (some reappear after disappearing from previous runs).
One should not use these maps for information to support a view that an area is “safe” to repopulate.
