The historic district also includes the remains of a large number of industrial and domestic features, some of which are visible ruins and some of which are known below-ground sites. Despite the knowledge of these below-ground sites, a professional archeological survey and evaluation has not been completed to verify their location, integrity and significance. Thus, this nomination does not justify significance under criterion D in the area of archeology. However, significance under archeology can be added to the nomination at a later date, if information potential is documented by professional archeologists.
Above-ground, visible ruins, however, have been identified, described, located on a map, verified through documentary research and counted as significant features within the context of thedistrict’s major themes (under criterion A, in industry) . There are 28 contributing features in this category, divided into 5 structures, whose original configurations and functions are apparent from their remains, and 23 sites, whose original configurations and functions were determined through documentary research. Each of these features is described individually below. [Nos. in the following list refer to Nos. given features on an 1892 Sanborn map.; these features are further keyed by number in bold to a location on one of the three enlarged area maps: Maps A, B, C]. While the existence of each of these ruins during the period of significance was verified through Sanborn maps, documentation was not always precise enough to determine exact dates of construction, builders and uses; thus these ruins are grouped by physical location, rather than according to association with the various cement companies.
