Big Pole Fire

The Big Pole fire about an hour west of here is out and quiet. I mapped it last week and sent the data to the BAER team. Here's an example of how I mapped the severity. When I got the satellite imagery, I edited the Incident perimeter and cut 2,000 acres off their number. They had been pretty liberal with counting unburned acres and I think I had a better source for a more accurate perimeter delineation.

Overall, the fire wasn't that severe. You can see that most the high severity corresponds with the north-facing, more densely vegetated slopes. This is pretty common. More fuel = hotter fire = longer residence time = higher soil burn severity. You can also see the 12,000-foot Deseret Peak in the back right of the picture.
