Acknowledgments

We are very grateful to Jim and Carolyn Pride for the use of their land (the vineyard site) and for their ongoing generosity. We are also very grateful to George and Anita Thompson for the use of their property, and to George for his continued support and general guidance. Steve Pride has played an integral role throughout this project, and made important contributions to this paper. Biondo Biondi, Simon Klemperer, Jerry Harris, and Art Thompson have all made major contributions to this research project as a whole, and have provided valuable guidance throughout. The data presented in this paper were made possible by the sweat of those who swung the hammer: Mike Beman, Morgan Brown and Phil Resor. We also greatly appreciate the efforts of the many others who have swung the hammer as part of other data collection efforts. Financial support has been provided by The American Chemical Society's Petroleum Research Fund, an Achievement Rewards for College Scientists fellowship, the Stanford Exploration Project, the American Association of Petroleum Geologists Grants-in-Aid program, the Geological Society of America's graduate student fellowship program, the Colorado Geological Survey, and the Stanford Earth Sciences McGee Fund.
