The McCash Fire was located on July 31, 2021 around 7:00 pm. The fire is burning in timber with an understory of tall grass and brush in rugged, steep terrain in an area with limited roads and partially within the Marble Mountain Wilderness. The nearest towns are Somes Bar and Happy Camp, CA (Siskiyou County). Full suppression tactics of confine and contain are being used to fight the fire. Daily Operations Update Video: Each morning an operations video update will be posted on the Six Rivers National Forest Facebook page. The video will cover what firefighters are working on and the plan for the day.

Fuels are timber litter and understory, brush and short grass. Steep terrain, plentiful fuels and ongoing severe drought conditions are the main drivers of the active fire behavior. All sizes of fuels are very dry and available for consumption. Higher elevations and lower humidity are increasing fire behavior today.
Active surface fire is burning across the fire in timber litter, shrubs, with isolated torching, group torching, and crown runs in the canopy. Fire ran toward Titus Peak and burned across a dozer line south of Titus Peak. Fire is burning from Huckleberry Mountain on the northeast side of the fire south through the Marble Mountain Wilderness to Wooley Creek. Active fire spread is ongoing on both sides of Wooley Creek and in multiple drainages south of Wooley Creek. The southwest and west flank of the fire is being held in a burn scar from 2017. Smoke columns are developing enough energy to break above the stable layer of air. Steep slopes with conifers have been the primary areas of intense fire runs, and there are significant areas of shrub and timber litter burning in all areas.
Resources and equipment will continue suppression of spots, direct attack, and mop-up on fire spread where possible; primarily from Elk Creek west along the fire edge and then south along the fire edge down the Highway 96 corridor from Independence/Ferry Point. Scouting for indirect line and line preparation will continue across the fire. Holding the fire on Titus Ridge and the Chicken Ladder Road is of critical emphasis. Resources will continue scouting in the Somes Bar area and further south down Highway 93/Salmon River corridor. Structure protection group resources will continue to assess and prepare structures.
Night operations will patrol in Elk Creek, the Highway 96 corridor, in the Somes Bar area of the Salmon River, and will secure containment lines.
Planned actions described above may be adjusted if high winds or precipitation creates unacceptable risk to line personnel or makes unpaved roads unsafe to travel. The Little Marble Fire will be unstaffed due to predicted weather.
Projected Incident Activity:
Significant growth potential today due to low fuel moisture, high temperature, and low relative humidity. The fire in the Elk Creek drainage will continue to advance west challenging containment lines near Titus Ridge. The fire will continue to press the Chicken Ladder Road as it tries to move north down Elk Creek. Crown fire is expected up the tributaries of Wooley Creek to the south. Other spots around the fire will burn actively into the wilderness. Fire will continue to burn actively into the night. With poor recovery some areas will burn continuously all night.
On Saturday, significant precipitation is expected mid-day. High winds will accompany the front. Winds may help spread fire. Fire spread will decrease if precipitation is able to soak the receptive fuels.
The Little Marble Fire is also being managed by Great Basin Team 7. The Little Marble Fire is 100% contained at 14 acres. Estimated cost to date is $114,487. Personnel are being counted with McCash resources. Fire will be unstaffed September 18-19. One wildland fire module will return to the fire on September 20.
On September 20, transfer of command with AK Team 1 will occur at 0630.
Stable weather conditions were present over the fire Friday morning resulting in cool temperatures, light winds, and widespread smoke. As morning inversions lifted, a subtle increase in southwest winds slowly scrubbed the smoke away from the fire delivering ample sunshine and temperatures in the 80s. The Divided Sky IRAWS reported southwest winds of 6-9 mph with gusts near 15 mph. Humidity levels were a little higher on Friday as onshore flow developed. Afternoon humidity values generally dropped near 25% across most of the RAWS near the incident.
A strong cold front will pass over the fire Saturday bringing the first autumn storm system for the season. Strong southwest winds are expected to accompany the frontal passage with potential for wind gusts near 45 mph across the ridgetops and 20-30 mph in the lower elevations. The front will bring the potential for moderate to heavy rainfall and over an inch of rainfall in some spots. High rainfall intensities will lead to a concern for flash flooding and debris flows near the burn scar. Steady rain will transition to showers Saturday night and early Sunday before precipitation comes to an end Sunday afternoon. Southwest winds look to remain breezy into Sunday morning before weakening and shifting to the west and northwest throughout the day. A warmer and drying trend will return Monday and Tuesday as weak offshore flow develops pushing temperatures back into the 80s.
