Context
shallow basin hearth originating from an erosion surface at the top of a slopewash deposit. Wood from Hearth A-3, found directly above an area of thermal oxidation. Hearth was a concentration of charcoal and burned rock, showing no evidence of purposeful preparation. The area of discoloration meas. 33 x 41 cm. Artifacts in the hearth included a basally notched Type VI arrow point, a reused drill of Table Mountain jasper, a C/N Type V arrow point,, a bifacially retouched cutting tool, and 2 obsidian flakes.
