The High Lava Fire in Skamania County, Washington has reached 95 percent containment across its 2,899-acre footprint, fire officials reported this week, with crews now focused on final mop-up operations ahead of an incoming precipitation system that is expected to help extinguish remaining heat sources.
The fire burned in Skamania County in southwest Washington, in terrain characteristic of the southwest Cascades—a landscape of mixed conifer forest, steep ridgelines, and drainages that can produce complex fire behavior when warm, dry conditions coincide with east wind events off the Cascades.
Approaching Full Containment
Reaching 95 percent containment is a major operational milestone, transitioning the incident from active perimeter management to mop-up phase. Crews are now systematically working through the interior of the fire’s 2,899-acre footprint, extinguishing burning stumps, logs, and subsurface root systems that can retain heat for days or weeks after surface fire activity has ceased.
Thorough mop-up is essential to prevent any reignition and escape of residual fire outside the established containment line. The incoming cold front, expected to deliver rain across southwest Washington this weekend, will provide significant assistance with final mop-up by cooling and moistening remaining heat sources within the perimeter.
Skamania County Fire Season in Review
Skamania County and the southwest Washington Cascades experienced above-normal fire activity during the 2026 season, consistent with the broader pattern of extreme conditions across the Pacific Northwest. The Columbia River Gorge and adjacent Cascades terrain present unique fire management challenges: steep slopes, dense timber fuels, and the influence of both marine air from the west and dry continental air from the east create conditions where fire behavior can shift rapidly with changing winds.
The High Lava Fire joins a growing list of Washington incidents that are either fully contained or nearing final containment as the region’s fire season draws to a close. Washington state reported significant fire activity across more than 413,000 acres during the 2026 season, with most incidents now contained or managed to minimal activity levels as fall weather arrives.
Closures and Access
Any area closures associated with the High Lava Fire will remain in effect until fire managers determine conditions are safe for public access. Smoke from residual mop-up operations may still be visible on cooler mornings when temperature inversions concentrate surface emissions in valley drainages near the fire area.
Visitors and recreationists should check with the Gifford Pinchot National Forest for current closure information before entering the fire area. The U.S. Forest Service and Washington Department of Natural Resources will maintain patrol resources in the area to detect and respond to any activity that develops from residual heat sources during the mop-up period.
