GEOLOGIC RESEARCH

Over the past two decades, we have focused our research efforts on understanding how climate change in the northern hemisphere impacted the Chesapeake region between 42,000 and 11,600 years ago. As a result, we have unearthed evidence (i.e., wood, pollen, and phytoliths), which tell us about how the upland forest and plant communites changed over this period of time. We have also found a few Pleistocene faunal remains (i.e.,teeth, shown below).
