Age. Late Wisconsin. Probable source of Pleistocene fauna with a date of 12,300 ± 600 BP (Huckell and Vance 2003) for the Conglomerate Layer from which the fossils are thought to have originated. In the preface (1975) to the second printing of Haury (1950), a date of 11,300 ± 1200 was given for the Volcanic Debris Layer.

General Description. Huckell and Vance (2003): A rock shelter in the Castle Mountains formed by erosion of poorly consolidated material at the junction with overlying basalt. A spring is present. The pertinent strata are the volcanic debris layer and the underlying agglomerate. The original excavation was in 1941 and the major report by Haury, with others, in 1950.
Ventana Cave became well known for the apparent association of extinct fauna and human-produced artifacts. However, a later series of radiocarbon dates in a block of material left by Haury indicate mixing of the volcanic debris layer, and the current interpretation is that the source of the extinct fauna in that layer is the underlying conglomerate (Huckell and Vance 2003).
