Sparks fire investigators are searching for two men seen leaving the scene of the Earthstone Fire, just before the fire was called in. One of the men was wearing a hat, and the pair were in a small blue or black two door vehicle. The fire started about 1:45pm Monday near Belmar Drive and Earthstone Drive near Los Altos Parkway in East Sparks. It has since burned more than 26, 700 acres, with containment at 30%. Residents in the Amy and Hockberry roads area are urged to evacuate to the Ironwood Equestrian Center on Whiskey Springs Road.
