Features

Wall: other (Feature 5) Top of page
General description
Wall that encloses the rim complex.
Use history
Wall served to delineate space on top of cliff.
Associated features
Another section of this wall (F-9) was exposed in Segment 4; F-8 is considered an associated feature because it appears to have served as a buttress to this wall.
Excavation procedure
Exposed during excavation and documented.
Portion excavated
Portions within excavation unit.
Horizontal location
Wraps around rim complex enclosing architecture and open space; exposed at north end of 1-x-1-m 495N 533E and at south end of 1-x-1-m 496N 533E.
Vertical location
Wall rests on Surface 1, which is defined as the top of sterile deposits (Stratum 2 in PD record; Strata D and F on Map 231).
Construction
Built on sterile sediment using large, unshaped pieces of sandstone; see Masonry forms for architectural details.
Remodeling/ modification
Yes. From Slide 611-30.
Thermal alteration
Yes. From Slide 611-30.
Sooting
Yes. From Slide 611-30.
Sealed
Yes. From Slide 611-30
Preservation
Poor.
Degree of preservation
Wall leans to the south and stones are missing as a result of natural deterioration; the presence of a wall (Feature 8), believed to have been a buttress for this enclosing wall, suggests that this wall may have been unstable during prehistoric times.

Wall: other (Feature 8) Top of page
General description
Buttress for wall that enclose the rim complex (Feature 5).
Use history
May have provided support for part of enclosing wall (F-5); another possibility, that would need to be further tested, is that this wall partitioned space within Nonstructure 2.
Associated features
F-5, enclosing wall.
Excavation procedure
Exposed and documented.
Portion excavated
Portion within 1-x-1-m unit 495N 533E.
Horizontal location
Adjacent to and south of enclosing wall (Feature 5); along west profile of 1-x-1-m 495N 533E.
Vertical location
Rests on Surface 1, which is undisturbed sterile sediment (Stratum F on Map 231; Stratum 2 in PD record).
Construction
Built on sterile sediment using sandstone and mortar; constructed after enclosing wall (F-5) was built; see masonry screens for architectural details.
