Fire to control fire.
You never know when to expect this but the low level smoke hangs in the air so it’s not a complete surprise.
The sides of the dirt roads can smolder for a week or more.
During a controlled burn the grasses and brush are on fire yet only a few of the trees are completely burnt. Most heal and grow stronger. This was the first time I know of a tree blocking the road and burning. We passed it before it fell, and there is another road out from here.
When you drive down this old road in a month, the land is green again.
