A wildfire flared up Tuesday near Covelo, Mendocino County and raced through brush, grass and timber. About 60 homes were ordered evacuated. Another fire north of Sacramento destroyed more than 1 1/2 square miles of grassy ranchland in a few hours. Continuing to burn are twin fires straddling Mendocino and Lake counties that have burned seven homes and threaten 12,000 more. And the seventh most destructive wildfire in California history is only 30 percent contained in the area of Redding. The Carr Fire has killed six people and destroyed 965 homes.
