- Context
- Structure 1 floor, E. wall. The structure is a partially burned, circular, semisubterranean structure with a central hearth complex. It meas. 4.47 x 4.66 m. Floor badly destroyed by root and rodent action. Floor is unprepared, use-packed natural caliche. The point of floor and wall contact ranges from 22-11 cm bmgs. Walls are unplastered, and top of walls are eroded away. NE Zea mayser is the only area showing signs of oxidation from burning of the superstructure. Superstructure probably a 4-post system. Ten additional secondary posts, set at an angle, provided additional support. A stringer trench is also present along the W edge of the floor. Hypothesized (no direct evidence) that the superstructure was primarily brush and/or hides covering a framework of posts. No wood in any of the postholes. Thus, the framework may have been removed upon abandonment. Entry may have been through a short ramp in the S wall (the only wall segment where no stringer trench or wall height is present. Altogether: 25 floor features. Hearth complex: hearth, sandstone deflector, and pit. Hearth is oval, basin-shaped, excavated into the caliche, oxidized. Meas. 45 x 50 cm, 6.5 cm deep. An area of heavy oxidation on the floor and wall long the E side of the structure. This area was covered by burned juniper branches, and 4 or the 5 14C samples were collected from these burned branches. This layer is up to 5 cm thick. What is thought to be a stringer trench-- a shallow linear trench at the base of the W wall-- is present. Trench is ca. 660 cm long, 2924 cm wide and 6-9 cm deep. Floor also has a very small bell shaped cist located along the S wall, W of the entry. Mouth of cist is 30 x 15 cm. Max interior dia. is 32-24 cm, with a max depth of 19 cm. 14 and and secondary postholes are present, 4 of which are main supports.Possible entry on the S walall is a sloping ramp-like area, 55 cm long. Floor artifacts: 8 lithic artifacts, 9 pieces of FCR, and a metate, face down.
