Smoke has been recorded lying over this ground six times so far. The thickest of it was thin between 1:00pm and 4:30pm local time. The last of those windows closed 136 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.
