JURUPA VALLEY, Calif. -

Riverside County firefighters are taking on a 150-acre blaze in Rancho Jurupa Regional Park that is burning near a number of homes and buildings.  Two homes were damaged.

Flames and huge plumes of smoke were visible from long distances.
    
There were no reports of any injuries or homes or buildings burning.
