A National Park Service investigation team is sifting through the blackened hillsides and ash left by Yosemite's 7,500-acre Big Meadow fire, probing what went wrong two weeks ago when a planned burn escaped control lines and prompted the evacuation of the small community of Foresta.
The investigators will conduct a forensic review of the fire that ran out of control Aug. 26 after embers ignited timber and chaparral surrounding the 90-acre grassy meadow being burned by park officials. The blaze eventually required more than 1,300 personnel and $15 million to contain, making it the second most expensive firefighting effort this season on public lands nationwide.
The situation has embarrassed Yosemite officials, whose management of one of the crown jewels of the park system is habitually under scrutiny. Tall columns of smoke were visible from the heavily visited Yosemite Valley, and flames forced road closures during the busy summer season.
The "prescribed" fire escaped its intended boundaries on the same day that a series of rock falls from the Royal Arches formation closed the swanky Ahwahnee Hotel for two days.
The park's acting superintendent defended Yosemite's fire team as "the best in the business."
