Higher humidity and cooler temperatures aided firefighters in their battle Sunday against a 2,116-acre wildfire along the eastern Sierra Nevada.
Fire information officer Franklin Pemberton said the fire was 45 percent contained Sunday night and no structures were threatened.
He said helicopters and air tankers helped keep the fire to ridgelines and well away from homes in the Coleville area about 70 miles south of Reno, Nev.
Late last week, officials were concerned that high winds could push the fire down canyon to a Marine housing unit north of Coleville and homes in the Topaz Lake area of Nevada.
The housing unit is used by the U.S. Marine Corps Mountain Warfare Training Center in Pickel Meadows near Sonora Pass.
About 400 firefighters were battling the blaze, which shut down a stretch of U.S. 395 on Friday night. The highway was open the rest of the weekend.
No major injuries were reported.
Firefighters contained two smaller wildfires in the area. All three fires were touched off by lightning Friday or Thursday.
The main fire still threatened habitat for both mule deer and the threatened Lahontan cutthroat trout, Pemberton said.
There was no estimated containment time for the blaze burning in brush and pinon-juniper forests.
