Geology Field Trips in and around the U.S. Capital

Edited by Christopher S. Swezey and Mark W. Carter

Prepared in conjunction with the Southeastern and Northeastern Sections Joint Meeting in Reston,
Virginia, the four field trips in this guide explore various locations in Virginia, Maryland, and West
Virginia. The physiographic provinces include the Piedmont, the Blue Ridge, the Valley and Ridge,
and the Allegheny Plateau of the Appalachian Basin. The sites exhibit a wide range of igneous,
metamorphic, and sedimentary rocks, as well as rocks with a wide range of geologic ages from
the Mesoproterozoic to the Paleozoic. One of the trips is to a well-known cave system in West
Virginia. We hope that this guidebook provides new motivation for geologists to examine rocks
in situ and to discuss ideas with colleagues in the field.
