ENTIAT, Wash. -- The U.S. Forest Service says the 675-acre wildfire between Entiat and Chelan was human caused.
Meanwhile a Sunday thunderstorm started a second fire nearby and is burning between 50 to 100 acres on the east side of Chelan Butte.
Officials say the land burning is a mix of private, state and federal. The fire is burning in steep terrain in shrub steppe fuels.
Officials say the first fire in Navarre Coulee remained within containment lines. The fire is 75 percent contained and is burning areas of steep terrain with hazards from rolling rocks.
About 200 firefighters are working those blazes.
