The Line Fire ignited on September 5th at around 6:00 p.m. PST along Baseline Road,[5] near its intersection with Alpin Street in East Highlands. The fire was originally named the Baseline Fire. The fire spread from that point into the San Bernardino National Forest.[6]

The CAL FIRE Incident Management Team 3 was activated on September 6th.[7]

On September 7th, the fire began to expand rapidly into the San Bernardino Mountains, prompting evacuation orders for the communities of Running Springs and Arrowbear Lake.[8] Governor Newsom declared a State of Emergency in San Bernardino County, authorizing the use of a Fire Management Assistance Grant (FMAG) from the Federal Emergency Management Agency (FEMA). [9]

The California National Guard was deployed, including four UH-60 Blackhawk helicopters, two C-130 aircraft, hand crews, and one military police company to assist with evacuations.[10]

As of September 12, 2024, the fire has burned 37,588.7 acres (15,211.6 hectares) and is 21 percent contained.[3]
