EPHRATA — A fire broke out Tuesday in the northern portion of the Y formed by State Route 17 and State Route 282, according to first responder alerts.

The fire, a few minutes southeast of Ephrata was reported a little before 6 p.m. and had burned an estimated 500 acres. The fire resulted in a closure of SR 17 between SR 282 and State Route 28 to ensure public safety. A cause was unknown but initial reports indicated it began at the Ephrata Gun Range. The fire, named the Marksman Street Fire, was fully contained at about 7 p.m.

The Dearinger fire, which has been burning in the North Cascades about 40 miles northeast of Everett since June 22, is 80% contained at 48 acres, according to the Western Washington Incident Management Team.

“The fire site has presented significant challenges due to steep slopes, rocky surfaces, rolling debris and dangerous standing trees,” wrote Incident Commander Josh Riepe in a statement Saturday. Riepe also thanked the nearby community of Darrington for its support and warm hospitality to firefighters.

The 4,758-acre Pioneer Fire on the eastern shore of Lake Chelan was 7% contained Monday, according to the National Interagency Fire Center. Warm, dry weather and increased winds are expected to make firefighters’ jobs more difficult in the next few days, the NIFC wrote in a statement. The small communities of Manson, Chelan and Stehekin are all open to visitors for the holiday week, the NIFC added.
