SLO County Cal Fire crews help battle blaze near Hwy. 41

Cal Fire crews from San Luis Obispo County headed to the Kern County line Monday afternoon to join emergency personnel from Monterey and Kern counties battle a large grassfire near Highway 41.

The fire was reported near the Cottonwood Pass area at about 3:45 p.m. and had burned about 60 acres of grassland about an hour later.

A Cal Fire spokesman said that Cal Fire air units are dumping retardant and creating a barrier between the fire and the highway but an additional 50 acres were under threat from the fire.

Five Cal Fire engines, one water tanker and a bulldozer as well as four aircrafts were deployed from San Luis Obispo County to the scene.

The Cal Fire spokesman said officials do not yet know what caused the fire.
