is the official point of origin on the interagency record.
Conditions measured 12.4 miles from the fire: 38°F, air at 94% humidity, a 11 mph wind out of the north-west.
Six other fires are burning inside the same view. Red Tail Hawk Ave Fire started 585 minutes before this one, 0.1 miles north, and has reached an unrecorded size. Stick Fire started 1065 minutes before this one, 0.1 miles north, and has reached an unrecorded size. 5061 Mule Deer Fire started on Friday 2 October, 0.1 miles north, and has reached an unrecorded size. Buffalo Fire started on Saturday 12 September, 0.2 miles north, and has reached an unrecorded size. Causeway Fire started on Wednesday 30 September, 0.3 miles south, and has reached an unrecorded size. Coyote Fire started 1095 minutes after this one, 0.3 miles south-east, 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 130 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.
