Six other fires are burning inside the same view. Lucas Fire started on Wednesday 9 September, 2.0 miles south-west, and has reached an unrecorded size. Bootstrap Fire started on Monday 5 October, 4.1 miles west, and has reached an unrecorded size. Bear Fire started on Thursday 24 September, 4.7 miles west, and has reached an unrecorded size. Gibby Fire started on Wednesday 2 September, 5.4 miles south-west, and has reached an unrecorded size. Test1 Fire started on Friday 28 August, 6.7 miles south-west, and has reached an unrecorded size. Prima Fire started on Monday 5 October, 7.7 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 1:10pm and 4:30pm local time. The last of those windows closed 23 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.
