Metal Detectors. To increase the likelihood of finding archaeological and historical sites, the CRS will use a metal detector during the field survey. A metal detector enhances field survey methods because it provides an additional method to aid in identifying metallic artifacts, particularly ones that are not readily identifiable in obscured surface areas. Metal detecting survey transects will involve one operator who sweeps the detector from side to side while walking back and forth in parallel lines across each area of investigation using (5m [16ft]) spaced transects (2.5m [8ft] on each side of the operator). Each ‘hit’ registered by the metal detector will be flagged and investigated upon completing survey transects with a second, more precise metal detecting wand used to pinpoint the exact location of the signal in the ground. The crew will document positive hits in field notes, GPS waypoints, and digital photographs. Due to the slower nature of the metal detector sweeps, the field crew will prioritize metal detector use at locations of known or suspected protohistoric and historic sites, higher potential landforms within the survey area, and at each newly recorded AHRS site.
