- Structure 1, sample from burned roofing or posts. Locus A. Structure was remodeled at least once. It meas. ca. 5 m in dia., possible floor area of ca. 19.5 sq m. Excavated into sterile, with lightly oxidized patches. Perimeter of floor is defined by a series of postholes, a linear distribution of slabs along 1 wall. 35 artifacts/mineral specimens found on floor, including ground stone, flakes, FSTs, ground stone, cobble tools, and bone. A small number of items were obsidian. Ground stone included 4 complete basin metates, 1 one-hand mano from the floor. Fill contained 2 strata: lightly burned roof fall and water deposited postabandonment sediments.2 hearths near the center (Features 7 and 10). Feature 10 is the earliest.; each probably represents separate occupations.
