Feature Numbers

The original excavators of the NAVAIR Quarter (18ST642) initially assigned numbers to twenty features.  After further examination in the field, eleven of those twenty features were determined to be rodent burrows.  Those eleven features were given feature numbers but not recorded or excavated.  They are not in the DAACS database. The remaining nine features were excavated and recorded.  These are in the DAACS database. The exclusion of the eleven numbered but not excavated and recorded features explains the gaps in the feature numbers in the Archive.  All Feature Numbers have a F-prefix, which precedes the number (i.e. F01 equals Feature 1). Some features were bisected and excavated in natural levels. All feature sediment was screened through ¼-inch mesh. Additionally, one liter samples were removed from each feature and water-screened through fine mesh for faunal and botanical recovery.  

Feature Groups

Feature groups are sets of features whose spatial arrangements indicate they were part of a single structure (e.g. structural postholes, subfloor pits, and hearth) or landscape element (e.g. postholes that comprise a fenceline). Feature Groups assigned by DAACS have a FG-prefix, which precedes the number (i.e. FG01 equals Feature Group 1).
