Feature 15b.—Badly weathered, fragmentary metates; altered “lumps” of sandstone; manos; and core tools. Three small pestles were found near association.
Feature 15c.—Inverted, killed, sandstone metate; sandstone slab; and core tools. Burial 11 was in close proximity, but owing to its badly disturbed condition, no positive association could be made with the feature.
Feature 15d.—Metates; altered sandstone blocks; core tools; manos; and fragments of human leg bones.
Feature 16.—Disintegrated, pitted metate and fragments of 2 other metates; mano fragments; core tools; unworked stone; and unidentifiable fragments of human bone.
Feature 17.—Characterized by a number of symmetrically water-worn cobbles. Contrasts with other features wherein metates, manos, cores, and irregular, unutilized stones predominate. Fragmentary metates, manos, and core tools were also present, as were 2 segments of human femora.
Feature 18.—Badly weathered, inverted, deep-basin metate in near association to symmetrical sandstone cobble containing a ground depression. The latter may represent the initial stage of mortar manufacture, though the smoothness and regularity of the depression surface somewhat invalidates the idea.
Feature 19.—Metates (deep basin, shallow basin, and slab); mano fragments; scraper planes; core hammerstones; and fragments of human femora and tibiae. The deep-basin metate was right side up, in contrast to the usual inversion.
Feature 20.—Deep-basin metate with associated metate fragments; carbon-smudged blocks of disintegrated sandstone core tools; and sections of human femora.
Feature 21 (pl. 18, b).—Large, shallow-basin metate and fragments of 2 others; 2 large, reworked, granite boulders; 3 blocks of highly decomposed sandstone; core tools; mano; and fragments of human femur.
Feature 22 (pl. 20, b).—Deep-basin metate; 2 slab metates and 3 metate fragments; chunks of altered sandstone; core tools; and a large, chert blade.
