Type sites:

Mesa Verde N. P.: Sites 103, 102, 786. La Plata district: Site 33. Mancos Canyon: Site 11. (Breternitz et al:30).

Dating:

Pueblo I (mid to late). AD 775 – 900. 
     Middle and Late PI, AD 775-900 (Wilson and Blinman:47).
      P I contexts, AD 775-900 (Varien: Appendix A(1)) .
      AD 750-900 (Reed, Erik K., 1958:79, cited in Cattenach:210).
      AD 700-750 beginning development at House 3, site 167 (Hayes and Lancaster:114).
      At Badger House, pottery is completely Piedra ~875, changing to Cortez ~AD 900 
             (Hayes and Lancaster:114).
      AD 750-900 (Lucius and Breternitz:19).

Texture:

Medium (Breternitz et al:29).
Very fine texture on bowl interior surfaces (Cattenach:210).

Temper:

Crushed igneous, medium to coarse; rock and sherd; rock and sandstone; 
      sherd and sand (Cattenach:210).
Crushed rock, some with sand (Hayes and Lancaster:114).
Crushed igneous (Breternitz et al:29; Varien).

Slip: 

None (Cattenach:210).
23% in later proveniences (Hayes and Lancaster:111).
Mostly unslipped, but 27-47% in La Plata area; 10% on Wetherill Mesa. Less 
       frequent in western areas (Breternitz et al:29).
Unslipped early, increasing with time (Varien:Appendix A(1); Wilson and Blinman:47).

Paint: 

Usually mineral (Cattenach:210).
Mostly mineral but 3.8% organic at Badger (Hayes and Lancaster:114).
Fired brown less frequently than Chapin (Breternitz et al:29).
Fugitive red on exteriors (Varien:Appendix A(1), less often than Chapin (Wilson and Blinman:47).
Paint primarily on bowls, only on interiors; some pitchers have simple, linear designs 
      (Hayes and Lancaster:114, 117). 

Polish: 

Low luster polish on most; almost all are wiped and rubbed (Cattenach:210).
Usually some (Breternitz et al:29; Varien:Appendix A(1)).
Quality of polish improves with time (Wilson and Blinman:47).
Increasing incidence (Hayes and Lancaster:114).

Rims: 

Solid or plain (Wilson and Blinman:47).
Solid paint (Cattenach:210). 
Solid paint or plain. Quite tapered, rounded tip (Breternitz et al:29).

Shape:

Seed jars are spherical. 
Pitchers have gourd shape and neck, no distinct shoulder. 
Handles are solid and round (Hayes and Lancaster:114, 118). 
Occasional exterior coil marks or tooling like Moccasin and Mancos Gray (Breternitz et al:30).

Design:

In general, Piedra moves away from the Chapin bottom-centered and radiating patterns to more rim-oriented designs and below-rim bands (Hayes and Lancaster:114). Both Chapin and Cortez design elements are found, including: 
     Barbed, ticked, and squiggled lines 
     Fairly simple panels or encircling designs
     Large units of parallel lines 
     More coverage than Chapin 
Later Piedra examples at Badger House show: 
     Lines embellished with delicately-flagged or tipped solid triangles
     Bands of parallel lines used as divider elements
     Long bands of parallel, corner-turning lines (also in P I Cibola style (Kiatuthlana), and Cortez)
     Wavy lines over a guideline 
     Increasing solid triangles
     A few checkerboards (Hayes and Lancaster:114)
Jar bodies may be ‘wrapped’ with parallel lines (Varien:Appendix A(1).
