The Fork Fire started in the Crystal Basin near Gerle Creek under critical fire weather conditions on 9/8/2020. 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.
As of this last Sunday, the fire was burning approximately 20 miles from Foresthill, the size of the fire was1,752 acres with
containment of 7%. The total personnel at the fire scene is 237. There are 4 Crews, 2 Helicopters, 9 Engines, 2 Dozers and 6 Water Tenders fighting the fire.
The incident meteorologist predicted southwest winds over the ridges, potentially aligning in the Rubicon
River drainage this last Sunday and Monday. Combined with lower humidity, these conditions could lead to critical fire weather. If the
smoke begins to lift out of the area, this is a strong indication of changing weather conditions.
On Saturday, crews focused on strengthening the lines east and south on the Fork Fire to prevent fire movement toward
Gerle Creek and Airport Flat. On Sunday, firefighters shifted their work toward the north and east where winds may push fire activity
and test containment lines. Crews will continue to mop up and hold the south side of the fire area. Firefighters have identified a
planned fire line near the southwest edge of the fire toward the South Fork of the Rubicon River. Crews continue to scout for safe
containment options further west across the Rubicon River, although steep topography and weakened snags present many
potential challenges. On the northeast side near Little Deer Creek, a containment line was established and improved. In preparation
for the critical fire conditions, the crews will attempt to use helicopters and Super Scoopers to cool active fire spots along the
northeast edge, if weather
Warm and dry conditions with poor humidity recovery will continue, leading to near critical fire weather conditions each afternoon.
A temporary flight restriction is in place over the fire area.
The Eldorado National Forest is closed until further notice as part of a regional temporary emergency closure.
