Immediately after the October 2004 flood, the preservation department worked quickly to store all the damaged maps in five freezer containers to prevent mold growth. The low temperature caused the mud and clay to freeze into fernlike (dendritic) patterns. To remove the mud, the maps were placed on spun polyester to prevent tearing, and washed in a large sink. Some maps had water-soluble ink, so conservation technicians grated erasers and used the crumbs to wipe away the mud. They were then stacked between boards and dried with a specialized fan. If the maps were still curled after drying, the staff used a humidifier dome to encase the paper and gradually introduce moisture to flatten the map. Maps that were ripped or torn were treated by leaf casting -- using paper pulp to fill the holes.
