This expedition was led by Marilyn Fox of the Yale University Peabody Museum to locate and collect fossils to be returned to Yale for preparation and become available for research. An articulated specimen of an Aetosaur (Typothorax) was collected along with several random bones. The area is a designated wilderness so the 250 pound specimen had to be carried out by hand.

Marilyn was accompanied by Alan and Alana Gishlick - Yale PhDs, Adam Belke - Yale PhD student, Leon Claessons - assistant professor, College of the Holy Cross, Emalee Blumhagen - Holy Cross student, Zach Lavender - Holy Cross student, and Lou Tremblay.
