Damage description: "The damage to the Del Valle Adobe at Rancho Camulos was very extensive. Two walls of the southeast bedroom (Ramona’s room) collapsed. The south wall of the bedroom at the southwest corner of the building collapsed, and the damage to the west wall is irreparable. The gable-end wall at the southeast corner was severely damaged but did not collapse. The stone walls at the north end of the west wing have suffered severe crack damage in the comers. Crack damage occurred throughout the building. There was damage at building comers in the form of pounding and separation gaps between walls at intersections, spalling of interior and exterior plaster, and spalling of adobe in areas that had been weakened by previous and repeated exposure to water. In many locations, the walls have pulled away from the ceiling joists, and damage to the walls has reduced their ability to support the joists."
