Three other fires are burning inside the same view. Auxiliary Fire started on Wednesday 5 August, 4.5 miles south-west, and has reached 0 acres. Calgary Fire started on Sunday 27 September, 4.1 miles west, and has reached an unrecorded size. Yankee Fire started on Thursday 30 April, 3.1 miles south, and has reached 0 acres. Their heat is counted against them, not against this fire, and the pale rings on the map mark where they are recorded.

Smoke has been recorded lying over this ground four times so far. The thickest of it was thick between 1:00pm and 4:30pm local time. The last of those windows closed 144 hours ago, so what is overhead now is not known.

Where the heat is

No cluster large enough to call a separate front. The heat is in one piece.

Conditions measured 4.8 miles from the fire: 81°F, air at 11% humidity, a 11 mph wind out of the south-east.

How it got here

Two days of record on a day-7 fire

The record here begins at 2:16pm on 9 Oct and runs to 2:00am on 10 Oct — 12 hours, 6 readings of heat. The fire is on day 7, so the first 5 days are missing: nothing showed up from above until the fire was large enough and the sky over it clear enough for it to be seen. There is no long arc to draw yet. What follows is what has actually happened.
