A brush hearth that began Thursday afternoon is burning within the hills close to Mount Hamilton Highway.
The Clayton Hearth was reported round 2:30 p.m. Thursday east of Clayton Highway. Inside about six hours, it had burned 66 acres (0.1 sq. miles) and was 30% contained, stated the Santa Clara unit of the California Division of Forestry and Hearth Safety.
No evacuation orders or warnings had been issued, although the fireplace approached houses within the By way of de la Vista and Three Springs areas, close to the Grandview Restaurant. Thirty constructions had been threatened, Cal Hearth stated.
