Features

Wall: other (Feature 6) Top of page
General description
Extramural masonry wall.
Use history
Does not appear to be part of a strucuture; it may extend to a D-shaped tower (Structure 28); wall is tied with the enclosing wall indicating the walls were constructed at the same time; wall may delineate a boundary/serve as a partition within rim complex.
Associated features
F-5; enclosing wall.
Excavation procedure
Exposed during excavation and documented.
Portion excavated
Portion within Segment 4.
Horizontal location
Between wall that encloses rim complex (Feature 5) and a tower (Structure 28); runs north-south in excavation unit and is perpendicular to enclosing wall.
Vertical location
Base of wall built in trench that originated from Surface 7; Surface 7 is a semi-altered surface of sterile clay and constructional fill.
Construction
Trench excavated into sterile clay; footer stones and basal stones were placed in trench and remainder of wall was built; large, unworked sandstone blocks were used to construct wall.
