Update: 10:30 p.m. - Containment Holds Steady as Crews Mop-up to Prevent Hotspot Activity

The American Fire grew by another 1,000 acres Thursday, but aggressive action has bolstered containment lines, while crews work to prevent the fire from spreading across the boundaries.

A total of 17,796 acres had burnt in the Tahoe National Forest by late Thursday, with 1,812 people working the incident. 

Fire Status: Crews continued to mop up on the west and north sides of the fire to prevent any fire from potential hotspots from crossing established containment lines. Today fire crews continued to hold and improve containment lines on the north-east and east sides of the fire. Aggressive fire suppression efforts have limited fire movement south to south-west along the North Fork of the Middle Fork of theAmericanRiver.

Efforts to contain the fire along the more difficult steep and hazardous terrain on the south and south-east perimeters has been very successful and that area will now be patrolled for hotspots.

The fire is established in Antoine, Manilla and Scewrauger Canyons and below the Barny Cavanah Ridge. Consumption of heavy fuels will continue to contribute to smoke in surrounding areas. An additional camp is in operation on the east side of the fire to reduce travel times for firefighters in division Z.
