As the sun came up Wednesday morning cameras showed the Radford Fire near Big Bear Lake in Southern California was very active. A 12:20 a.m. mapping flight found that it had grown to about 980 acres and had spread 0.4 mile north of Skyline Drive/FR 2N10. At that time it was between the two ski areas, Snow Summit and Bear Mountain, but was still high on the slopes, about 0.8 mile from Switzerland Drive.

The Radford Fire has burned hundreds of acres in Southern California just south of the Snow Summit Ski area which is south of Big Bear Lake (see map above). It started north of Highway 38 in the Barton Flats Area. Tuesday morning the fire was burning on the south-facing slope below Snow Summit. At about 11 a.m. the lens on the Snow Summit South camera was suddenly coated with red fire retardant. There is infrastructure on the mountain that will be important for firefighters to protect.

When the FIRIS mapping aircraft was over the fire at 11 p.m. Monday 332 acres had burned and spot fires were growing out ahead of the main fire. At about 11 a.m. Tuesday the San Bernardino National Forest reported it had grown to 450 acres. Looking at the views from several fire cameras at 11:30 a.m. today the fire was very active and appears to be spreading vigorously.

The article was edited Sept. 7 to show that a single helicopter dropped water on the fire Monday night, not retardant. Helicopters dropped retardant that night at the nearby Fairview fire.

  1. What does it mean when the article says “The Radford Fire was reported at 1:30 p.m. on September 5th by a US Forest Service Helicopter while conducting lightning reconnaissance.” What is a lightning reconnaissance? They need to explain.

    1. It means that lightning was observed in the area so the area was reconnoitered to search for fires that may have been ignited by the lightning. This is a standard procedure.

  2. Slight typo there sir. There were no helicopters dropping retardant on that fire on Monday night. Just one Type 2 helicopter contracted to USFS, operated by Helicopter Express, dropping water on it, and working alone all night long.

  3. Big Bear Lake and City are to the north of the Radford Fire path. Hundreds of structures maybe in the fire path.

  4. Is there any idea now, on Tuesday, which way this fire might go? I worked at Camp Osito Rancho many years ago. It is west of that ski area. At least the summer campers are gone. This is the second Girl Scout Camp that I have worried quite a lot about this summer, The first was Pine Creek Ranch on the Salmon River. Way back, as a kid, my first summer at GS Camp was in the Santa Cruz Mountains, 4 miles inland from the Pacific. Our unit was moved as the area we were meant to camp in had been burned the year before and the campers had been evacuated. That was in 1963. And was it only 2 (3?) years ago that much of Big Basin State Park, the oldest California State Park, burned. I camped there many, many times with large gatherings of Santa Clara County Girl Scouts throughout the 60s. For some reason I live in Florida now, but here it can rain 5″ in an hour. Not such a bad thing. I do hate to read about so much of my childhood going up in smoke.
