Test Trench II (TT II), Dry Cave

NM: Eddy Co.; 1280 m.

Location of the Test Trench II site

Age. 10,730 ± 150 (I-6200) on bone collagen; judging from fauna, this is too recent as often the case with bone dates. Based on the fauna, it probably is between 11,000 and 12,000 BP.

General Description. UTEP 54. The deposits are spill from the Bison Sink Fissure onto a ledge on the east side of Balcony Room (see diagrams at Dry Cave Introduction).

Discussion. This locality originally was part of UTEP 4 (Bison Chamber), but later assigned a separate locality number as it became clear that the two areas were separate in time.
