Excavation Each of the clearly separated strata at the site are being meticulously dug in 2 cm levels, all items being left in place, mapped, photographed, and cataloged individually. Excavations are concentrating on the uppermost sediments which rest on top of massive roof fall debris.
Artifacts are sometimes abundant and well preserved.
Immediately above this stratum is a series of irregularly shaped, repeated small burnings. Light from these fires illuminated the Red Horn composition. Most of the sediments provide instructive information on the source and mechanisms of deposition in the shelter and relate their local events to regional sediment and climatic episodes. Debris from the painting of the Red Horn composition is associated with the uppermost of these anthroseds, indicating that the artists were also making the anthroseds. Structures More than 100 feature numbers have already been assigned and the vast majority of these are hearths.
