I am very grateful to David Romano and Mary Voyatzis for their inviting me to participate in the Mt. Lykaion Survey and Excavation; and for their leadership in assuring that investigations of the Sanctuary of Zeus would be profoundly interdisciplinary. I have benefited from their fund-raising efforts, which provided travel and logistical support for students including students who assisted me in the field. Funding from Exxon Mobil helped defray some of my operational expenses in Greece during the summer of 2008.

I am indebted to Andrew Insua for his specific technical guidance in helping me to establish a GIS-based data framework for my geological investigations. Randy Goosen carried out the initial steps in transforming hard copies of maps, and spreadsheets of data into an ARC-MAP system in the midst of the 2007 field season, when she served as my assistant both for field work and computer support. Meridith Reifsneider expertly enhanced and streamlined my ARC-MAP data bases and files during 2008 and 2009. Stephen Ahlgren gave me complementary use of the stereographic projection software (StereoStat) he developed.

I want particularly to thank Tom Fenn, who was my field assistant during two two-week stints of geological mapping, in the summers of 2004 and 2005. We worked together at the very start of the project, and his observations and inputs were particularly useful as we attempted to make sense of the stratigraphy and begin to trace the geological contacts. In addition, I want to thank Phil Nickerson, who was my field assistant for a 4-week stint of fieldwork in the summer of 2008; and Karl Yares, who assisted me for 4 weeks in the summer of 2009.

This work would not have been possible without the overall and sustained support of the Anastasia Panagiotopoulou, who at the time of initiation of the project was the Ephor in charge of the 5th Ephoreia in Sparta, and Michalis Petropoulos, Ephor of the 39th Ephoreia of Prehistoric and Classical Antiquities in Tripolis.

Susie Gillatt, scientific illustrator, was instrumental in transforming preliminary line drawings into the final illustrations, which appear here in this article.

Finally, I am touched by the hospitality and practical support provided by the residents and leadership of Ano Karyes. The accomplishments to date would have been much more difficult to achieve without such a base of operation with dedicated laboratory space close to the Sanctuary of Zeus.
