Presentation Time: 8:20 AM

CORRELATING YOUNGER DRYAS CLIMATE AND ENVIRONMENTAL ADNA PRESERVATION AT CONNLEY CAVES, OREGON

How aDNA is preserved in archaeological sediments remains an ongoing and sometimes contentious topic. We present preliminary results gleaned from archaeological excavations at Connley Caves, Oregon. Utilizing both ancient sedimentary eDNA and micromorphology, we assess how climactic conditions during the Younger Dryas may correlate to ancient sedimentary eDNA preservation. Finally, we evaluate the pairing of micromorphologhy and ancient sedimentary eDNA analysis in this case-study and discuss its potential.
