This field trip was part of the 2009 Keck Geology Consortium Symposium, held at Franklin and Marshall College, Lancaster, Pennsylvania. This trip went to four localities: one to sediments in the bottomland of a small stream, and three to folded rocks including quartz conglomerate, dolomite and limestone, and sandstone. Note, my understanding of the geology in this region is limited, so let me know about any errors.
