• The fire continues to challenge control lines on the northwest and southwest fire line because of steep     inaccessible terrain and drought stressed brush, chaparral, and dead timber.
• The main water supply for the Hearst property and Hearst San Simeon State Park remained threatened.   The Hearst Castle and Hearst Castle Infrastructure continue to be threatened.
