Lightning has sparked four new fires in the Stanislaus National Forest, a Forest Service spokesperson said Tuesday.

Anna Payne, who was distributing information about the Summit Complex and Creek fires, did not provide locations of the four new fires. She said the new fires had burned less than one acre each.

The Summit Complex fires east of Donnell Reservoir had burned 4,653 acres. Payne estimated they are 30 percent contained.

The Creek Fire had burned 420 acres with no containment, Payne said.

Columbia Air Attack pilots did not assist Stanislaus National Forest personnel with any fires from Saturday to Tuesday afternoon, but a recon flight was conducted of Tuolumne County, Calaveras County and the 1,400-square-mile forest, according to Cal Fire.

Lightning may have sparked a 5-foot-by-5-foot spot fire reported at 6:31 p.m. Monday in the 200 block of Dowling Road in the West Point area, south of the North Fork Mokelumne River. People at the scene put the fire out. One engine crew responded and they reported “out upon arrival, extinguished by locals.”

The cause was described by Cal Fire as “tree on fire (possibly lightning).”

Another fire reported at 7:26 a.m. Tuesday burned a 10-by-10-foot spot in the area of Southgate Drive and Stockton Road in Sonora. Two engine crews and one supervisor responded, and the fire was declared contained at 8:26 a.m.

The cause of the fire is under investigation.
