In June 2010, the Schultz fire tore through northern Arizona, charring more than 15,000 acres, forcing the closure of several monuments and leading to the evacuation of hundreds of homes.
The fire had swept through hillsides along the San Francisco Peaks, and when monsoon storms followed, flooding triggered major debris flows that caused extensive damage to a pipeline that is a prime water source for nearby Flagstaff, Ariz. The pipeline collects water from a number of springs and delivers the water by gravity to the city's public works facilities.
