I spent some time tracking The River Fire in Mariposa and Madera counties this week, and it makes an interesting comparison to the 2020 CZU Lightning Complex Fire in Santa Cruz county and which I also covered in my blog. The River Fire started on 11 July. Its development is documented by maps from the NASA FIRMS system, which I’ve included below. Today, after four days, the satellites no longer detect fire in the area of the River Fire. The Calfire Incident Report indicates 21% containment and ongoing mop-up efforts.
