Smoke travels pretty far and causes obvious health issues. The undergrowth due to suppressing previous fires and the additional fuel from dead trees due to droughts result in very hot fires that grow huge. The Dixie fire that is ongoing is 762 sq miles and is 25% contained. It is the largest fire started from a single source and second largest overall in California history. If we let a fire just burn, will it just get so large that it can’t be contained and will just burn till there is nothing left? I read about natural fires that would span states and would burn till the rainy season. The fires currently burning in Siberia cover 4000 sq miles. The Bay Area is about 7000 sq miles. Alameda County is about the same size as the Dixie fire.
