Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 361. This field trip enables delegates attending the Twenty-eighth International Geological Congress to spend several days in the largest city in the United States. Local geologists have designed day-long field trips to acquaint participants with the complex geology of the New York city metropolitan region. The papers included in this book will serve as guides to the planned trips but may not necessarily follow the order in which the trips will be scheduled.
