Case S. Documents and Lack of <br />Land Disturbance of a Historical <br />Archeological Site in an Urban <br />Setting: An eighteenth - century house <br />in a Colonial -era town has been <br />nominated. The townhouse is located <br />on a deep lot maintained as lawn and <br />gardens. Historical research confirms <br />that the current property lines were <br />established in the original plat of the <br />block in the 1700s and that substantial <br />construction has never occurred. <br />Archeological investigation of other <br />houses in the urban area has revealed <br />the presence of associated buried <br />privies and trash deposits. <br />Discussion: Historic documenta- <br />tion of legal boundaries would be the <br />most appropriate in this case where <br />the documentation confirms that <br />current property lines represent the <br />historic property lines. In addition, <br />the lack of interior block disturbance <br />is documented, leading to an expecta- <br />tion of buried feature remains such as <br />privies. This expectation maybe <br />confirmed by surface observation of <br />site features and materials. Subsurface <br />testing would not be necessary for <br />boundary definition in this case. <br />Modern legal boundaries should be <br />used in concert with historic docu- <br />mentation which confirms that the <br />current legal boundaries are histori- <br />cally the legal boundaries of the site. <br />Case 6. Documents and Lack of <br />Land Disturbance for a Multiple <br />Property Nomination for Charcoal <br />Iron Furnaces: Numerous charcoal <br />iron furnace complexes and associ- <br />ated communities have been identi- <br />fied. All known examples of this class <br />of property are included. Although <br />predominantly subsurface in nature, a <br />few aboveground resources are <br />present. Archival research and <br />intensive restoration of one of the <br />furnace complexes have established a <br />description of the types and functions <br />of the resources represented, their <br />time range, their physical characteris- <br />tics, and the probable classes of <br />important research data represented. <br />Original plats for individual furnace <br />complexes and communities as well <br />as historic photographs are available. <br />Limited archeological surveys have <br />confirmed the presence of historically <br />documented features at several of the <br />furnace sites and associated commu- <br />nities. Typically, the iron furnaces <br />and associated communities have not <br />been developed following their <br />abandonment. <br />Boundary Description: For each <br />furnace complex and associated <br />community, the boundary is defined <br />by the historical limits of the resource <br />as illustrated in historic plat maps and <br />verified as undisturbed based on field <br />inspection (See Figure 5.) <br />Boundary Justification: Given that <br />all members of this class of resources <br />have been identified; that the original <br />plat are available to establish bound- <br />aries; that archival research, restora- <br />tion, and limited archeological <br />research have established the types <br />and functions of the various resources <br />represented; and that the furnace sites <br />are located in a region of the State that <br />has experienced little development, it <br />is appropriate to use historic docu- <br />ments (plats) to determine the bound- <br />Dries of each property included in the <br />nomination. Subsurface testing is not <br />necessary for boundary justification, <br />because enough is known about the <br />site functions and features to accu- <br />rately predict Iocations of activity loci <br />and expected data classes. Limited <br />surface reconnaissance on several <br />properties and restoration of one <br />furnace and auxiliary building have <br />confirmed the presence of expected <br />features, based on historic documen- <br />tation. Visible signature features, <br />such as furnace stack remnants, <br />earthen ramps, slag dumps, ore pits, <br />and building foundations in conjunc- <br />tion with plats, historic photographs, <br />and standing buildings have been <br />useful in locating specific features, <br />i.e., stacks are located near streams <br />TYPICAL CHARCOAL IRON <br />FURNACE LAYOUT <br />(2025 ACRES) <br />` FURNACE STACK, BUILDING <br />REMNANTS AND SOME EQUIPMENT <br />REMAIN <br />FESTORAGE SHEDS <br />BRIDGE HOUSE <br />FURNA BL <br />STACK <br />i <br />ENGINE FOUNDRY ❑ <br />HOUSE <br />CAST SHED ❑ <br />MANAGER'S WORKERS' Q <br />HOUSE HOUSING O ❑ <br />N COMPANY 0 El <br />STORE <br />& OFFICE <br />ROAD <br />Figure 5.
