Holy Fire (2018)

The Holy Jim Volunteer Fire Department (HJVFD) is a group of firefighters in remote "Holy Jim Canyon" in the Cleveland National Forest in Orange County, California. The chief of the department is elected to the position by members of the community and department. The members of the fire department are certified and trained in basic life support and fighting wildfires. The department performs 2 to 3 rescues of lost hikers a year and maintains its own stationhouse, one fire engine, six 5,000 gallon water tanks, a mile of water lines in the canyon and maintains its own weather station gauge at the stationhouse.Orange Coast Magazine featured a four-page article on the firefighters in October 2008.The station house now has only one fire engine. The other engine, Gertrude, was donated to a museum.

Trabuco Canyon National Forest was established by the U.S. Forest Service in California on July 6, 1907 with 153,387 acres (620.74 km2) when the name was changed from Trabuco Cañon Forest Reserve and land was added. On July 1, 1908 the forest was combined with San Jacinto National Forest to create Cleveland National Forest and the name was discontinued.

Santiago Peak is the southern mountain of the Saddleback landform in Orange County, California. It is the highest and most prominent peak of both the Santa Ana Mountains and Orange County; it also marks a border point with Riverside County. The peak is named for Santiago Creek, which begins on its southwestern slope. During most winters, snow falls at least once on the peak. A telecommunication antenna farm with microwave antennas sits atop the peak. The Acjachemen referred to the peak as Kalawpa, with the nearby village of Alume meaning "to raise the head in looking upward," in reference to the mountain.

The Santa Ana Mountains are a short peninsular mountain range along the coast of Southern California in the United States. They extend for approximately 61 miles (98 km) southeast of the Los Angeles Basin largely along the border between Orange and Riverside counties.

Saddleback, sometimes called Old Saddleback or Saddleback Mountain, is a natural landmark formed by the two highest peaks of the Santa Ana Mountains and the gap between them. Resembling a saddle as viewed from most of Orange County, California, this landform dominates the county's eastern skyline. On the clearest days, Saddleback is visible from most of the Greater Los Angeles area. Santiago Peak is the highest peak in the range and the highest point in the county at 5,689 ft (1,734 m). Modjeska Peak is the second highest at 5,496 ft (1,675 m). The two peaks form part of the border between Orange and Riverside counties. The hilly landscape in south Orange County is known colloquially as Saddleback Valley, and hence many institutions are named after Saddleback, including Saddleback Church, Saddleback College, and the Saddleback Valley Unified School District. The presence of volcanic rocks in Silverado Canyon indicates that Saddleback Mountain was formed prior to the development of the San Andreas Fault, back when a subduction zone occurred where the Pacific Plate went under California.

Trabuco Peak is a 4,607-foot (1,404 m) summit in the Santa Ana Mountains on the border of Orange and Riverside Counties, California, about halfway between Rancho Santa Margarita and Lake Elsinore. The mountain sits on the divide between Arroyo Trabuco (Trabuco Canyon) on the west and the Temescal Creek valley on the east. Situated in the Cleveland National Forest, it is the highest summit in the Santa Anas south of Santiago Peak.The main trails providing access to the peak, the West Horsethief and Holy Jim trails, both begin at the bottom of Trabuco Canyon. The Main Divide Road, a fire road, also passes close to the peak.

Los Pinos Peak is a 4,455-foot (1,358 m) summit in the Santa Ana Mountains in Orange County, California, about 8 miles (13 km) east of Rancho Santa Margarita. Los Pinos is the southernmost peak above 4,000 feet (1,200 m) in the Santa Anas, and provides extensive views south towards San Diego and the Pacific Ocean as well as views (on clear days) of the San Jacinto Mountains and San Bernardino Mountains in the east. The summit rises rather prominently above the main crest of the Santa Anas and is conspicuously visible from much of southern Orange County, although its actual topographic prominence is only about 610 feet (186 m).The peak is situated in the Cleveland National Forest and is accessible by the Main Divide Road (a fire road); the Trabuco Canyon Trail, which begins near Trabuco Creek, and the Los Pinos Peak Trail, which begins in Hot Springs Canyon (near San Juan Canyon, San Juan Creek and the Ortega Highway (State Route 74).

Modjeska Peak is the northern mountain of the Saddleback landform in Orange County California. It is the second-highest peak of the Santa Ana Mountains, after Santiago Peak, whose summit is less than 0.6 mi (0.97 km) to the northwest. Modjeska lies within Cleveland National Forest and, despite being shorter than Santiago, has a smaller peak without manmade structures to obstruct views of the Pacific Ocean and San Gabriel Mountains. The peak is named after the Shakespearean actress Helena Modjeska, who lived in Modjeska Canyon (on the western foot of the mountain) near the end of her life.

The Airport Fire was a wildfire that burned 23,526 acres (9,521 ha) in the Santa Ana Mountains in Southern California in September and October 2024. The fire destroyed 160 structures in Orange and Riverside counties and caused 21 non-fatal injuries. At its peak, 20,780 structures were threatened by the fire. The fire was accidentally ignited on September 9, 2024, by Orange County Public Works employees conducting fire prevention measures in the unincorporated community of Trabuco Canyon. It spread towards the city of Rancho Santa Margarita and eastward into the Santa Ana Mountains, where it crossed over the ridge of Santiago Peak into Riverside County. The Airport Fire forced mandatory evacuation orders in various Southern California communities, particularly in Lake Elsinore and along Ortega Highway where many structures were damaged or destroyed. The incident happened concurrently with the Line Fire in San Bernardino County and the Bridge Fire in Los Angeles County, straining available firefighting resources and creating a smoky, unhealthy air quality that reached as far as Las Vegas. California governor Gavin Newsom declared a state of emergency in response to the fires.
