The Sourdough Fire north of Diablo Lake started on Saturday, July 29. It is currently burning in the Ross Lake National Recreation Area within the North Cascades National Park Service Complex, in very steep terrain. As of this week it was 7,377 acres and 25% contained. Fire behavior increased last weekend with the unseasonably hot, dry, and unstable conditions. The fire grew approximately 1,000 acres, mostly in the Stetattle Creek drainage. Firefighters utilized aerial delivered water resources extensively for suppression efforts in the Sourdough Creek area which successfully kept fire west of the drainage. More information on what trails and campgrounds are open can be found here and here.
Hwy 20 is open. This remains an active fire area and the road is subject to closing again with little notice based on fire behavior, fire mitigation strategies or weather. Travelers along SR 20 are advised they may encounter firefighting personnel and apparatus along the highway and are discouraged from stopping along this stretch of highway. Traffic control is in place for the safety of the traveling public and should be observed.
Road closure information is posted in the WSDOT real-time travel center and @wsdot_north and @wsdot_east on X/Twitter and updates will be provided as available. Details about recreation in this area including trail, area and camp closures are available on the North Cascades National Park Service complex website and the U.S. Forest Service alerts website.
