With geophysical techniques, we will search for Paleo-Indian archaeological features around the famed Bull Brook site. Though recognized among the largest and oldest Paleo-Indian sites the U.S. (ca. 12,000 years old), the surrounding areas have not been fully investigated. We presently don't know how large Bull Brook really was. We will attempt to answer this question, and additionally seek to clarify the site's age, which is also a point of contention.
