That puts it less than a mile west of the footprint of the very large Ferguson Fire which burned more than 96,000 acres in 2018. It was caused by a hot catalytic converter on a vehicle that parked in dry grass July 13, 2018 along Highway 140 near the Savage Trading Post.

The Oak Fire at Midpines, California was active throughout much of Friday night, growing by about 2,200 acres between 10 p.m. and 4:25 a.m. Saturday when it was mapped by FIRIS at 6,555 acres. Half an hour after sunrise it was putting up two smoke columns that were quite some distance apart, with one of them creating enough energy to be capped by a pyrocumulus cloud.

Just to be clear — wildfires normally lay down at night, providing an opportunity for firefighters to move in closer and put in direct fireline. It is not common for a fire to be burning so actively soon after dawn that it is creating multiple smoke columns, especially a pyrocumulus column.
The Mariposa County Sheriff has ordered evacuations as far south as Highway 49 and east to Jerseydale. Their map is available online. As we wrote earlier, this is a dangerous fire.
The Oak Fire is spreading rapidly. When it was mapped at 4:25 a.m. Saturday it had spread south across Triangle Road and reached Darrah Road. At that time it was about a half mile west of the community of Darrah. Firefighters were planning a burning operation between Triangle Road and Darrah Road west of the town.

EPN106 of OnScene.TV got some excellent shots of helicopters and air tankers dropping on the Oak Fire near Yucaipa, California November 29. It burned 99 acres off Oak Glen Road and was caused by a vehicle over the side of the road.
If the video below does not start, you can see it on YouTube.
Firefighters benefited from light winds, cooler temperatures, and the fact that the San Bernardino air attack base was only 12 air miles away.
The next day Neptune’s Air Tanker 12, a BAe-146 under contract with CAL FIRE, was released for the season.

California: Oak Fire stopped at 100 acres
A fire in California that reportedly had a great deal of potential was stopped at 100 acres Tuesday by an aggressive initial attack. The Oak Fire northeast of Sonora was reported at 1:23 p.m. and was attacked quickly by troops on the ground, S-2s that were 10 minutes away at Columbia Air Attack Base, a very large air tanker, and a C-130. The Oak Fire and another fire nearby, the Hill Fire, burned together which then was only referred to as the Oak Fire.
KCRA reported that firefighters attending training at a nearby conference center had to be evacuated.
