CACHE CREEK WILDERNESS AREA – Officials say a wildland fire in the Cache Creek Wilderness Area burned more acreage on Wednesday morning.

The Oasis Fire, which started Monday evening south of Highway 20 and six miles west of Highway 16, was reported to have burned 1,350 acres by midday Wednesday, according to Cal Fire. The cause is under investigation.

The fire currently is at 40-percent containment, with Cal Fire officials estimating full containment on Friday.

On Wednesday morning, six air tankers and five helicopters were making drops on the fire, said Nancy Carniglia with Cal Fire.

That air contingent was small compared to the nearly 1,100 firefighters on the ground, Carniglia said.

Moderate wind conditions weren't causing issues for firefighters on Wednesday, but Carniglia said weather conditions were expected to be hot and dry – with temperatures in the high 90s and low humidity.

Because there are no established roads in the fire area, bulldozers have played a big part in fighting the fire. In addition to building new fire lines, Cal Fire reported the dozers are reopening old dozer lines and improving them to allow vehicles access.

On scene Wednesday were 50 engines, 41 fire crews, five helicopters, 15 dozers and 13 water tenders, according to Cal Fire.

The costs for suppression to date are approximately $461,965, Cal Fire said.
