- composite sample, upper and lower organic lenses in yellow loess
- Comments
- MfVa-9: Artifacts and charcoal were associated with organic lenses within loess. Near the top of the slope, there appeared to be two lenses separated by sterile loess, but they merge into a single lens downslope. Since only small amounts of charcoal were recovered from the upper and lower organic lenses, they were combined to obtain S-2013. Analysis of pollen from the upper organic lens revealed concentrations of arboreal pollen slightly greater than expected from modern vegetation at the site, suggesting the possibility that more favourable conditions (Hypsithermal?) prevailed at the time. Artifacts included bifaces, cores, blades and microblades.
