The area you outlined matches up perfectly to the area that has been control burned over the past several decades. I know it well. Just for perspective of the size of this fire. I think that area highlighted is around 200 acres.In a day or two some satellite imagery should come up on Planet Labs that will show the extent in detail. Currently there's nothing available for the area in question since Saturday.
Edit: Imagery from yesterday at 11:54AM is now available.
It looks like there are several separate areas still smoldering. Because of the thin cloud cover/haze, I can't exactly outline the full boundaries. The highlighted section up to Jackson Road definitely burned.
