A fire has burned about 400 acres on the border of the Carson Iceberg Wilderness.

The fire, reported at about 2 p.m. Saturday, is a few miles west of the Slinkard fire, said U.S. Bureau of Land Management spokesman Mark Struble.

Called the Silver II fire, the fire was fought Saturday by two air tankers and two 20-person hand crews.

Hot shot crews, two more air tankers, three helicopters and an incident management team are being brought in today, Struble said.

Struble said the fire in Bagley Valley, about six miles due south of Monitor Pass, (California State Route 89) about a mile north of the wilderness area and was not threatening any structures Saturday night.

The origin of the fire is unknown, but Struble said an investigation team has been call in.

The haze of smoke that's hanging across northern Nevada is coming from hundreds of miles away, in Northern California and Oregon.

Forecasters say winds shifted on Friday, pulling the smoke into Nevada.

National Weather Service meteorologist Larry Osterman said the pall is expected to last through the weekend. It stretches along the Interstate-80 corridor from the Sierra to east of Elko.

A total of 14 major active fires, all started by lightning, had burned 258,000 acres in Oregon. The largest California fire is at 66,000 acres. It earlier threatened California's giant sequoias.

While the smoke is ugly, it's fairly light and mostly at higher elevations, which poses little health hazard except for people who are extremely susceptible to pollution.
