Six other fires are burning inside the same view. Lone Spot Fire started on Wednesday 12 August, 3.1 miles south-west, and has reached an unrecorded size. Fox Ridge 26 Fire started on Tuesday 21 July, 8.0 miles north, and has reached an unrecorded size. Ru339 Fire started on Sunday 5 July, 11.4 miles north, and has reached an unrecorded size. Cornfield 3 Fire started on Tuesday 21 July, 11.9 miles north-east, and has reached an unrecorded size. Little Willow Creek Fire started 15 minutes after this one, 12.3 miles east, and has reached an unrecorded size. Greyhawk Rd. Fire started on Wednesday 8 July, 13.1 miles north, 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.
