Context
Structure 1, Locus 3. No clear evidence of the structure prior to excavation. The top of the structural fill was 10-15 cm bmgs. The structure was roughly D shaped, with a slight dish shaped floor. It meas 2.50 x 3.15 m, ca. 15 cm below the prehistoric ground surface. The floor was unprepared. A line of large sandstone blocks, many of which were broken metates, were along the S edge, forming the flat part of the D shape. No evidence of postmolds or of a clear entryway was found, with the exception of a break in the line of sandstone blocks. A low clay wall extension in the SW part of the floor was possibly part of a metate bin. The fill was darkly stained charcoal, representing the remains of the superstructure. The latter was probably brush, given the lack of large pieces of wood charcoal or jacal. The fire that burned the superstructure caused some scorching of the floor. A slight depression in the S-central part of the floor may represent a small warming hearth, It was 40 cm in dia., 5 cm deep, with the same fill as that above the floor. The depression may simply be a depression in a somewhat uneven floor. Sampling the floor for microrefuse produced 17 small flakes, 11 faunal remains, and importantly, a single small piece of Textile consisting of several fibers arranged in an s twist, identified as Linum (flax) Floor artifacts: a total of 116, 107 flakes, 8 pieces of ground stone, 2 flake tools, 1 core tool, and 1 Elko C/N proj pt, 4 rabbit sized bone frags., 1 unidentified bone, 41-50 uncharred Chenopodium seeds, burned juniper and pinyon wood, 2 charred Zea mays kernels. Pollen from the floor metates were dominated by juniper and sagebrush, along with Cheno-Ams.
