A controlled burn is planned for Monday in the Shasta-Trinity National Forest.
This will be in the area of Blue Rock Road, about four miles north of Weaverville.
The Trinity River Management Unit is planning the burn to remove dead vegetation and reduce the risk of future wildfires.
Smoke will be visible for two to three days along China Gulch Road, Little Browns Creek, and Browns mountain.
A total of 78 acres may be burned, depending on weather conditions and safety other considerations.
