Mechanical Removal of Plowzone and Other Sediments
The mechanical removal of plowzone may be implemented only upon consultation and with the approval of WVSHPO staff, and should be stipulated in any scope of work or data recovery plan. Plowzone removal may be conducted in areas that were subject to previous cultivation practices and that exhibit a definable plowzone.
Plowzone removal may be used in previously cultivated areas to facilitate the identification of subsurface features. The degree of plowzone removal shall be determined by the intensity of the investigation effort. Plowzone removal during Phase II investigation should be as non-invasive as possible in order to protect the integrity of the site. Removal during data recovery efforts may be as extensive as necessary to identify subsurface features. It is also acceptable to mechanically remove sediments in order to reach buried archaeological deposits, if buried deposits are known to be overlain by culturally sterile soils (i.e. fill).
Phase II Investigations
Following the removal of plowzone, the area should be shovel-scraped or trowel-scraped to expose a clean surface for inspection and identification of subsurface features. A detailed discussion on feature excavation and sampling strategies is found in the sections titled Feature Identification and Sampling Procedures.
Phase III Investigation



The mechanical removal of the plowzone may be implemented during Phase III investigations in areas that were subject to previous cultivation practices and that exhibit a definable plowzone. During Phase III investigations, plowzone removal may be conducted to expose large, contiguous areas of the surface in order to identify sub-plowzone features.
