YOLO COUNTY (CBS13) — The Yolo County Landfill was the site of a raging fire early Thursday morning.

It appears the fire started a little after 1 a.m. at the landfill along County Road 28H between Davis and Woodland.

Davis Fire crews say shredded tires caught fire. A lumber storage area nearby was threatened by the flames, but the area is otherwise rural.

Flames were raging through the early morning hours, shooting a large plume of smoke into the air. By 6 a.m., the fire had calmed down but was still visibly smoldering.

Firefighters were able to contain the flames to the shredded tire area. About a 1/2 acre was burned, Davis Fire say.

Exactly what started the fire is now under investigation.
