Thousands of residents remained out of their homes Monday morning as the 51-square-mile Sand Fire continued to burn in Southern California's Santa Clarita Valley.

"This fire, what we've seen in 72 hours, is almost unprecedented," said Los Angeles County Fire Department Battalion Chief Dennis Cross. "We'd have to go back a long way to compare a fire to this. And, we're not through with this thing yet"
