UPPER LAKE, Calif. – The Mendocino National Forest reported that firefighters are approaching full containment on a wildland fire burning since Saturday on the Upper Lake Ranger District.

As of Tuesday afternoon, the High Glade Fire had burned 305 acres and was 70 percent contained, according to forest spokesperson Tamara Schmidt.

The fire previously had been estimated to have burned 350 acres. Schmidt said the reduction in acres is due to more complete and accurate mapping of the fire perimeter.

Full containment is expected by the end of the week, she said. Smoke will still be visible as interior fuels continue to burn.

Visitors are asked to avoid the area due to increased fire traffic. Several roads are closed in the area; visit www.fs.usda.gov/mendocino to view Closure Order 08-13-09 for more detailed information.

The High Glade Fire was spotted early Saturday morning. The cause of the fire is under investigation, Schmidt said.

She said the Tuesday afternoon update on the fire was expected to be the final one from the forest headquarters unless significant activity occurs.
