Features

Pit: not further specified (Feature 2) Top of page
General description
Small, elliptical pit.
Use history
If this is a pit feature, it appears to have been excavated into secondary refuse deposits, then later covered with other secondary refuse deposits. This feature, however, may be a rodent burrow instead as the fill is extremely loose. Arguments for it being a feature include the verticality of the walls and the fact that it very definitely has a base.
Associated features
None.
Excavation procedure
Upper third of pit was cut through before the pit was recognized in plan view; after recognition, fill inside pit was excavated separately.
Portion excavated
Portion within Nonstructure 4, Segment 2.
Horizontal location
Along the north face of Nonstructure 4, Segment 2.

Originated from Surface 3, which is the top of a secondary refuse deposit (Stratum B in PD record).
