Horse Fire has grown to about 160 ha (400 acres) south of Clear Creek Campground, near Schell Mountain, west of Lakehead in Shasta County, California, as of July 3. The fire was ignited by lightning associated with an intense storm system that delivered over 12 000 cloud-to-ground lightning strikes across northern California.
According to fire officials, the fire has not crossed Rattlesnake Creek, a key containment reference point. Ground crews and aerial assets including tankers and helicopters are actively engaged in suppression efforts. Firefighters have made good progress on both the head and flanks of the fire, with containment lines being extended overnight.

The region was hit by a high-intensity lightning event between July 1 and July 2, resulting in multiple wildfire ignitions across Shasta-Trinity and Klamath National Forests. In the Shasta-Trinity National Forest, at least 17 fires were confirmed, many of them small and quickly contained.
Klamath National Forest alone recorded 3 860 strikes between June 30 and July 1, with multiple new fires, including the Caroline, Springs, Ridge, Nest, and Grouse fires, all held to minimal acreage by rapid response teams. Across the two forests, aerial surveillance, smokejumpers, helicopters, and fixed-wing tankers were mobilized to monitor and suppress newly detected fires.
Officials from the U.S. Forest Service described the lightning outbreak as “a very high-end lightning event.” The risk of additional fire starts remains elevated due to forecast dry thunderstorms, and Red Flag Warnings are in effect across multiple northern counties.
This pattern mirrors past large-scale lightning events in California, including the August 2020 outbreak, which produced similar lightning counts and ignited over 500 wildfires across the region.
