It looks like it is hitting an inversion. Still, it looks larger than anything else I’ve seen in Marin for some time.

Blackstone Canyon. Southeast of Big Rock Ridge. Gets the morning sun. Steep. Brushy. Fire roads on nearby ridges but depending on how far it’s spread it could easily burn a couple hundred acres just because of access issues.

Marin Fire has done a ton of prep work on this ridge in the past several years. Still a lot of fuel up there, but much better than it was a few years ago.

The last major fire in that part and slope of Blackstone canyon hasn’t burn since late 60’s. Novato chief burned severely, multiple structures lost.
