Excursions in Geology and History: Field Trips in the Middle Atlantic States

The 2006 GSA Annual Meeting in Philadelphia provided a unique venue for the geologic and historic exploration of the Middle Atlantic States. Excursions into Geology and History is a collection of 13 papers and accompanying field guides that explores topics ranging from fossil plants of the Pennsylvania Anthracite basins, to the use of slate as a building stone, to the structural geology of Appalachian orogen transects, to coal basin mine fires, to the geological influences on the outcome of the Civil War battle at Gettysburg, America’s most hallowed ground. The book will prove to be a valuable educational resource for geologists and historians alike.

Abstract
A thick sequence (45+ m) of Cretaceous age Potomac Group sediments unconformably overlain by Quaternary Trenton Gravel and Alluvial silts and clays was investigated as part of the planning for and construction of a new 1525-m-long (5000-ft) runway (Runway 8–26) at the Philadelphia International Airport. This runway was constructed over a deleted but deed-restricted U.S. Environmental Protection Agency Superfund site, the Enterprise Avenue Landfill. This sedimentary sequence contains three discrete aquifer units, several of which are included within the recharge zone of the federally designated New Jersey Coastal Plain Sole Source Aquifer. This paper presents an overview of the...
