During July and August 1993, staff from the Office of History and Archaeology of the Alaska Division of Parks and Outdoor Recreation spent four weeks conducting a historic buildings survey in Flat, Iditarod and nearby mining camps (Figure 1). This work was carried out under a Cooperative Agreement between the U. S. Department of Interior, Bureau of Land Management and the State of Alaska, Department of Natural Resources to document and evaluate historic properties associated with the Iditarod National Historic Trail.
