is the official point of origin on the interagency record.
Conditions measured 12.5 miles from the fire: 46°F, air at 80% humidity, a 15 mph wind out of the north-west.
Six other fires are burning inside the same view. Shack 26 Fire started on Tuesday 21 July, 2.3 miles south, and has reached an unrecorded size. NH Playground Fire started on Sunday 13 September, 2.4 miles south-west, and has reached an unrecorded size. Rodeo GS Fire started on Tuesday 14 July, 2.5 miles south, and has reached an unrecorded size. EF Curb Fire started on Wednesday 15 July, 2.8 miles south, and has reached an unrecorded size. Habitat 1 Fire started on Saturday 11 July, 3.2 miles south, and has reached an unrecorded size. 2 Mile Fire started on Tuesday 21 July, 3.9 miles south-west, and has reached an unrecorded size. 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 ten times so far. The thickest of it was moderate between 9:00am and 11:00am local time. The last of those windows closed 113 hours ago, so what is overhead now is not known.
No satellite heat has been attributed to this fire yet — either it is too new for a pass to have caught it, or it is too small to register from orbit. Everything above is from the interagency incident record and updates as that record does.
