Excavation and Data Recovery
Phase III: Excavation & Data Recovery
Phase III data recovery is done when an archeological site eligible for the National Register cannot be preserved from a project’s impact. The design for the PB-85 Stream Restoration and Wetland Creation project could not be changed to protect the archeological site. SHA ordered a Phase III data recovery project to save information and artifacts from the site before the wetland construction began. Data recovery on the BARC site began in summer 2012 and ended in spring 2013.
Phase III involved a two-step approach. First, archeologists dug additional test units looking for more cultural features. Then they mechanically excavated the sterile topsoil to reveal the Native American camp’s underlying cultural features.
Excavations revealed a surprisingly stable setting, despite the close proximity of two streams. Historic alluvium (sand, mud, or gravel deposited by flowing water) capped the site and preserved its integrity.
