Location of SQF Complex

SQF Complex or Sequoia Complex was a complex of two of the August 2020 California lightning wildfires, burning in Sequoia National Forest and adjacent areas. Sparked on August 19, it included the Castle and Shotgun fires. As of January 5, 2021, it has burned 174,178 acres (70,487 ha) and is 100% contained.[2] 228 structures were destroyed.

Property lost[]

The small community of Cedar Slope was largely destroyed by the fire with 57 of its 65 cabins completely burned.[3] In the nearby communities of Alpine Village and Sequoia Crest, 37 and 49 cabins were lost in the fire respectively. No structure damage was reported in nearby Camp Nelson or Ponderosa.[4] The area remains at risk for mud flows and flash floods due to the charred soil being unable to absorb water.[2]

Evacuations and road closures[]

As a result of the fire, parts of Route 190 and Route 198 were closed, Sequoia National Park was closed for two weeks [5] and parts of Three Rivers were under mandatory evacuation orders. The fire was burning in Sequoia National Forest, Inyo National Forest, and the Golden Trout Wilderness. On 14 September, the fire crossed the boundary into Sequoia National Park.[6][7] The SQF Complex was declared 100% contained on January 6, 2021.[8] The winter weather essentially extinguished the fire, although a sequoia tree trunk was found to be still burning in early May, 2021.[9][10]

Impact on Sequoia Groves[]

The Castle fire swept through portions of 20 Giant Sequoia groves. The number of mature Sequoia Trees that died is “certainly in the hundreds – and could easily top 1,000.” More recent estimates indicate that over 7500–10,600 mature trees, or over 10-14% of the species' population, could have been lost in the fire.[11][12] The most intense previous fire in this area is dated to 1297 based on tree ring data. The McIntrye Grove, a short distance to the south from Cedar Slope, is reported as heavily damaged. Near Sequoia Crest, one-third of the Alder Creek Grove of Giant Sequoia is reported as severely damaged.[13] The large Stagg Tree in Alder Creek Grove was not impacted. Other areas experienced “light fire” which is expected to be ecologically beneficial in the long run. The Homers Nose Grove is also reported as “badly burned”.[14]
