• cement type: for sandstones– silica, carbonate; and including known variations of“dirty” sandstone, white sandstone, red sandstone• degree of cementation/induration (readily crumbles, very hard and compact,splits along bedding planes, etc.)• structural properties, such as bedding planes, texture, etc.2. Artifact Typea. Basin Metate• Small basin (10–20 cm long, 1–3 cm deep)• Large basin (20–40 cm long, 3–10 cm deep)b. Trough Metatec. Slab Metated. One-hand Manoe.

Type (including number of grinding surfaces)2. Material Type3. Original morphology of stonea. blockyb. boulder/large cobblec. slabd. bedrock4. Degree and type of shaping of stone in addition to grinding surfacea. flaking of corners and/or edges to reduce bulk and/or shape stoneb. grinding to smooth finish5. Total length, width, thickness of stone6. Total length, width, and maximum depth of grinding surface7. Commentsa. grinding surfaces well-developed as opposed to showing minimal wearb. presence of tiny sharpening pitsc. presence of coloration/pigment staind. discoloration and spalling caused by burninge. etc.8. Samples to take (metate must come from a protected situation such as from structurefloor or bottom of storage or cache pit)a. pollen washb. macrobotanicalc. residue9.
