Five other fires are burning inside the same view. Bark 2 Fire started on Monday 31 August, 0.0 miles east, and has reached an unrecorded size. Bark Fire started on Sunday 30 August, 0.1 miles south, and has reached an unrecorded size. Curve Fire started on Thursday 27 August, 0.4 miles south-west, and has reached an unrecorded size. Cloud Fire started on Thursday 3 September, 0.4 miles south-west, and has reached an unrecorded size. Buffalo Fire started on Saturday 5 September, 2.7 miles north-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 10:00am and 12:00pm 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.
