The next formal update for the Fork Fire will be on Monday September 28th, unless conditions on the fire change substantially during the weekend.
The Fork Fire started in the Crystal Basin near Gerle Creek under critical fire weather conditions. Driven by east winds gusting 30-50 miles per hour, the fire grew rapidly to the west. It is burning in the Rubicon River drainage and the 2014 King Fire burn scar. The Rubicon canyon is in an extremely steep and remote area which makes firefighting difficult. This area of the King Fire had burned at high severity with nearly 100% tree mortality, leaving large snag patches of fire killed trees. The standing snags are a significant safety hazard, especially in strong winds. There is also a high concentration of dead and down trees creating a heavy fuel load, as well as dense post-fire regrowth of 4-6 foot tall brush.
