- MfVa-14: Radiocarbon samples were taken from the upper and lower levels of what appears to be a hearth near the crest of the slope. The upper portion of the feature corresponds to the lower Level II strata in the general profile (S-2270). The area contained a rather dense concentration of charcoal in association with ash, or ash mixed with beige loess and a substantial amount of chipping debris. The upper and lower portions of the feature were separated by a lens of largely sterile yellow loess. The lower hearth deposit, in upper Level III, yielded large pieces of charcoal, flakes, small specks of possible calcined bone, and ash (S-2271). A second hearth feature, in the Level II strata, containing large pieces of charcoal, some fire-reddened bedrock shatter, ash, and flakes was dated by S-2273. The third concentration of apparent hearth material occurred in the upper Level III strata. This feature yielded flake fragments and ash, associated with what appears to be burned soil, and was dated by S-2272. A small blade-like flake (possibly a crude microblade) was recovered in this feature. The stratigraphic consistency in the dates, with Level II at about 700-900 BP and Level III at 1700-1800 BP, lends some measure of assurance to the interpretation of the features as hearth deposits.
