Features

Bedrock feature (Feature 1) Top of page
General description
Shallow basin in bedrock; natural depression "enhanced" by pecking.
Use history
Function unknown; possibly used for tool manufacture or as a "pot rest"?
Associated features
Possibly nearby bedrock feature (Feature 2).
Excavation procedure
Feature was pecked into exposed bedrock, which later was covered with collapsed wall debris. Wall fall was removed from this bedrock feature as part of Stratum 1 of the nonstructure before the feature was recognized. The feature was finally recognized when an area of cleared bedrock was swept. PD 405 refers to the feature itself, not to fill or artifacts.
Portion excavated
All.
Horizontal location
Just outside west wall of Structure 1209, about midway along length of wall.
