In 2014 Centennial Archaeology, Inc. took a fresh look at an old site with a long, and in some ways tortured, history of research. Trinchera Cave, 28 miles east of Trinidad, was professionally excavated on four separate occasions between 1949 and 2001. Please join Christian J. Zier at the CU Museum of Natural History on Oct. 13 at 7 p.m. for a free lecture where he will discuss his findings and research.
