Marble Complex Helitack Crews at Scott Valley Airport on July 8, 2025

Current Situation: Firefighters are making steady progress across the Marble Complex, with the Summit Fire remaining the primary focus as it continues to show consistent daily growth. Crews are actively constructing and reinforcing control lines, especially along the southern flank where fire activity has been persistent. While the Jacket Fire remains quiet under patrol status, resources are committed to holding existing lines on both fires and ensuring all suppression efforts remain effective. Friday marks the last day of moderate conditions before an extreme heat warning takes effect, increasing the potential for more active fire behavior in the days ahead.

Summit Fire: The Summit Fire remains active, with multiple hotshot crews pushing in from the west side, steadily building direct control line along the southern flank. The most active areas of the fire are now also burning through dense timber litter, fueling steady heat and visible smoke. As crews make progress, the combination of suppression efforts and smoldering fuels means smoke production is likely to increase Friday. Meanwhile, crews on the north and east sides continue to make progress securing containment lines and mopping up hot spots, working to strengthen control and limit any further spread.

Jacket Fire: The Jacket Fire has reached 96% containment, a significant milestone for the Marble Complex. Visible fire activity has been minimal, and crews have successfully secured nearly the entire perimeter. While the fire has moved into patrol status, that does not mean the threat is entirely gone. Firefighters remain on scene, steadily monitoring the area to make sure no hidden hot spots reignite and undo the hard work already accomplished. Their focus now is on holding the line and ensuring the fire stays fully secured.

Weather: Friday will bring warmer conditions across the fire area, marking a transition ahead of an approaching heat wave. While temperatures today will climb, it’s expected to be the last relatively moderate day before an extreme heat warning takes effect. Beginning this weekend, higher elevations where the fire is burning could see temperatures rise into the high 80s and lower 90s, increasing the potential for more active fire behavior as fuels continue to dry out.
