Firefighters brace for strong winds
536-sq.-km fire in Yosemite National Park threatening to advance on three towns
GROVELAND, Calif. For 30 years, Ike Bunney has run a dude ranch amid the tall pines and steep canyons along the North Fork of the Tuolumne River in California’s Sierra Nevada. Now his 15 horses are safe in distant pastures as wildfire on the northern edge of Yosemite National Park threatens his mountain community.
“We’ve already evacuated the horses,” said Bunney, who was maintaining vigil Sunday at his Slide Mountain Guest Ranch. “I think they’re worried about the fire sparking over these hills.”
At the nearby Black Oak Casino in Tuolumne City, the slot machines were quiet as emergency workers took over nearly all of the resort’s 148 hotel rooms.
“The casino is empty,” said casino employee Jessie Dean. “Technically, the casino is open, but there’s nobody there.”
As thick smoke portends the fire’s fast approach, the area has been cleared of everyone but locals and emergency workers. Dean lives on the reservation of the Tuolumne Band of Me-Wuk Indians and left her four children at relatives’ homes in the Central Valley.
With winds gusting to 80 km/h on Sierra mountain ridges and flames jumping from treetop to treetop, hundreds of firefighters have been deployed to protect this and other communities in the path of the Rim Fire raging north of Yosemite National Park.
Eight fire trucks and four bulldozers were deployed to work near Bunney’s ranch on the west side of Mount Baldy.
Overnight the fire grew 18 square kilometres as firefighters gained little ground in slowing the now-536 squarekilometre blaze, said Daniel Berlant of the California Department of Forestry and Fire Protection.
“Today, unfortunately, we are expecting strong winds out of the south,” he said. “It’s going to allow the fire to advance to the northeast.”
Fire officials are using bulldozers to clear contingency lines on the Rim Fire’s north side to protect the towns of Tuolumne City, Ponderosa Hills and Twain Hart. The lines are being cut a mile ahead of the fire in locations where fire officials hope they will help protect the communities should the fire jump containment lines.
The high winds and movement of the fire from bonedry brush on the ground to 30-metre oak and pine treetops have created dire conditions.
“A crown fire is much more difficult to fight,” Berlant told The Associated Press Sunday. “Our firefighters are on the ground having to spray up.”
Officials estimate containment at just seven per cent.
The blaze sweeping across steep, rugged river canyons quickly has become one of the biggest in California history, thanks in part to extremely dry conditions caused by a lack of snow and rainfall this year. Investigators are trying to determine how it started Aug. 17, days before lightning storms swept through the region and sparked other, smaller blazes.
The fire is the most critical of a dozen burning across California, officials say. More than 12 helicopters and a halfdozen fixed-wing tankers are dropping water and fire retardant from the air and 2,800 firefighters are on the ground.
“This fire has continued to pose every challenge that there can be on a fire: inaccessible terrain, strong winds, dry conditions. It’s a very difficult firefight,” Berlant said.
Statewide, more than 8,300 firefighters are battling nearly 1,000 square kilometres of fires. Many air districts have issued health advisories as smoke settles over Northern California. On Saturday, organizers cancelled the 24th annual Lake in the Sky Air Show at Lake Tahoe because of poor visibility.
The Rim Fire has threatened two groves of giant sequoias that are unique the region, prompting park employees to clear brush and set sprinklers.
The towering trees — which grow only on the western slopes of the Sierra Nevada and are among the largest and oldest living things on Earth — can resist fire. However, dry conditions and heavy brush are forcing park officials to take extra precautions in the Tuolumne and Merced groves.
The U.S. Forest Service says about 4,500 structures are threatened by the Rim Fire. Berlant said 23 structures were destroyed, though officials have not determined whether they were homes or rural outbuildings.
The tourist mecca of Yosemite Valley remained open, clear of smoke and free from other signs of the fire that remained about 32 kilometres away.
