Age. Late Wisconsin. Bone Bed 2 radiocarbon dates are 10,230 ± 160, 10,100 ± 300, and 9920 ± 150; a date on charcoal associated with a horse-camel-mammoth deposit is 12,460 ± 490 for Bone Bed 1 (Dement 1986). Both bone beds probably contain earlier deposits, though without the main bone beds overlapping.
General Description. Other names applied to the archaeological site include Ice Box Cave, Bone Cave, Burned Bone Cave, and 41VV218 (the official designation). The site consists of a rock shelter in Mile Canyon, near Lantry. Located at the base of a cliff, the deposits record several bison jump incidents and an earlier, multilayer deposit (Bone Bed 1) unresolved as to whether associated with man or not. An excellent presentation with numerous photographs is available on the web at the Texas Beyond History site, and a portion of the information here is from that site.

Discussion. Three main deposits (bone beds) were recorded, some recording more than one incident. Bone Bed 2 and Bone Bed 1 date to before the end of the Pleistocene. The original descriptions of the archaeology (Dibble) and Bison bone analysis (Lorrain) appeared in Dibble and Lorrain (1968); identifications of miscellaneous faunal remains were by Frank (1968).
New excavations were carried out in 1983-1984, focused on bone beds 2 and 1 (Dement 1986).
