Two fire crews from the Valley are part of two separate strike teams sent to the Butts Canyon Fire in Napa and Lake counties.
Glen Ellen sent a Type I engine to the blaze, Kenwood sent a Type III, while Sonoma Fire and Rescue Authority Capt. Sean Lacy is a strike-team leader.
The Glen Ellen crew, consisting of Assistant Chief Matt Atkinson, engineer Marty Amon and firefighters Japen Soto and Will Powers, are on structure protection in the Berryessa Estates subdivision.
Glen Ellen Chief Peter Van Fleet thinks the crew could be released as early as Saturday.
The Kenwood crew, consisting of Assistant Chief Daren Ballach and firefighters Kayla Shubin and AJ Armanini, are part of a Type III strike team.
