YOSEMITE NATIONAL PARK, CALIF., AUG. 11 -- Yosemite National Park's spectacular sights, normally enjoyed by up to 25,000 visitors on summer weekends, were clouded by smoke today as 14,000 acres burned on the park's west side.
"There's next to nobody here," said Don Fox of the U.S. Park Service.
Yosemite was closed Friday after the first summertime evacuation in its 100-year history.
More than 175,000 acres were burning in northern California, with 14 fires classified as major and hundreds of smaller ones being watched.
More than 116,000 acres of forest land have burned in Oregon in recent days, and more than 90,000 acres burned in Idaho. Fires also have hit Utah and Washington.
About 11,000 firefighters were working on the California lines, mostly in pine forests. The largest fire, in Tehama County, had burned 106,000 acres by this morning, the California Department of Forestry reported.
The U.S. Forest Service requested help from the military today and was told that three Army battalions would be made available after undergoing three days of special training in firefighting.
Most of the California fires were started by lightning, officials said; 23,490 lightning strikes were counted in the state by electronic detection equipment between Aug. 3 and Friday. A fourth straight year of drought has increased the risk of fires.
"The good news today is that there were no lightning strikes overnight, and there shouldn't be any for several days now," Lisa Boyd of the California Department of Forestry said.
In eastern Oregon, firefighters held their own in efforts to corral forest and range fires burning across more than 116,000 acres.
Lightning storms continued, with 2,600 strikes reported overnight. But fire spokesman Doug Decker said the threat from lightning was abating after five straight nights of 2,000 or more strikes.
In Idaho, hundreds of firefighters labored to dig containment lines around forest and range fires, but thunderstorms crackling overhead in the central mountains promised yet another round of blazes.
Temperatures dropped below earlier highs over 100 in southern Idaho and some heavy rain even fell Friday night in the Payette National Forest north of Boise, although 19 new lightning-caused blazes began.
