The map above shows heat detected by a satellite on the Briceburg Fire at 3:42 a.m. Tuesday. It indicates growth on the north and east sides, some of which could be firing operations by firefighters to stop the spread.
CAL FIRE is reported at about 9 a.m. PDT Tuesday morning that it has burned 800 acres. Our very, very rough unofficial estimate leads us to believe that with the firing operation it could be twice that size.
The fire is on both sides of Highway 140 just west of the Sierra National Forest 12 air miles southwest of the El Portal entrance to Yosemite, 7 miles north of Mariposa, and one mile west of the Sierra National Forest. At 6:46 a.m. PDT Highway 140 was closed in the Briceburg area.

The Briceburg Fire burning on both sides of Highway 140 has required the closure of one of the roads leading into Yosemite National Park. Since the fire started October 6 it has burned at least 500 acres, according to CAL FIRE Monday afternoon. (see map above)
When smoke from the fire broke through an inversion Monday afternoon the intensity increased significantly.
Highway 140 that leads to an entrance on the west side of the park is closed near the small community of Briceberg. The fire is 12 air miles southwest of the El Portal entrance to Yosemite, 7 miles north of Mariposa, and one mile west of the Sierra National Forest.
At least eight air tankers were working the fire Monday afternoon in addition to multiple helicopters.
An evacuation order is in place for Briceburg Campground.

I’m headed to Mariposa County to cover the #BriceburgFire, which has shut down Hwy 140 near @YosemiteNPS. The fire is 250+ acres, and 0% contained. What’s worse: PG&E is monitoring a “severe wind event” right now.
