Minimal fire activity occurred on Tuesday, with a small increase in acreage. The South Fire is in the Shasta-Trinity National Forest, southeast of Tomhead Mountain, west of Red Bluff, and 15 miles south of Platina CA. The fire is in a remote and very rugged area of the forest. The western portion of the South Fire, within the Yolla Bolly Wilderness, continues to be confined south of Humbolt Ridge; east of Sanford Ridge; and north of Cottonwood Creek.
The eastern portion of the fire, which is being managed under a full suppression strategy, saw very little activity on Tuesday. Today, firefighters will focus primarily on improving and mopping up containment lines as needed to keep the fire within existing lines. Road repair operations will continue. The top priorities are to continue providing for firefighter and public safety; protection of private and Forest Service infrastructure; protection of natural and cultural resources; and limiting fire spread to within the established boundaries.
