|---|---|---|---|---|---|
| Sandia Cave Unit J | Hibben F. C. (1941) | there is a single 14C date of "870+/-110" years B.P. on "organic debris" but the unit spans most of the Holocene (Haynes and Agogino 1986) | siltstone | 0.0117 - 0 Ma Quaternary | |
| Sandia Cave Unit X (Bliss-Hibben Collection) | Hibben F. C. (1941) | this unit was thought by Hibben to include "Sandia" (pre-Folsom) artifacts, to be entirely "Late Pleistocene," and to underlie and predate units F and H, but according to Haynes and Agogino 1986 it consists of material reworked "by rodent activity" from units F, H, and J and the "Sandia" artifacts are actually of Folsom age; there are nine 14C dates ranging from "1890+/-90" years B.P. on a "charcoal lump" to "13,700+/-400" on "large animal bone," but the youngest of six dates on bone is "8,520+/ | siltstone | 0.126 - 0 Ma Quaternary | |
| Sandia Cave Unit X (Haynes Collection) | Hibben F. C. (1941) | this unit was thought by Hibben to include "Sandia" (pre-Folsom) artifacts, to be entirely "Late Pleistocene," and to underlie and predate units F and H, but according to Haynes and Agogino 1986 it consists of material reworked "by rodent activity" from units F, H, and J and the "Sandia" artifacts are actually of Folsom age; there are nine 14C dates ranging from "1890+/-90" years B.P. on a "charcoal lump" to "13,700+/-400" on "large animal bone," but the youngest of six dates on bone is "8,520+/ | siltstone | 0.126 - 0 Ma Quaternary | |
| Sandia Cave Units F and H | Hibben F. C. (1941) | thought by Hibben to be a single "Folsom" unit of "Late Pleistocene or early Recent age"; for unit H there are 14C dates of "9,100+/-500" years B.P. on "breccia organics" and "12,830+/-490" on "bone organics," and for unit F there is a date of "12,000+/-400" on "breccia organics"; the unit H "bone organics" also have a rejected uranium-series date of "73,000+/-4000" (Haynes and Agogino 1986) | breccia | 0.126 - 0 Ma Quaternary |
