Along the Wissahickon Creek
Originally called Wisauksicken and Wisamickon by the Lenni Lenape tribe of southeastern Pennsylvania, the creek was renamed Wissahickon by European settlers in the late 1600s. The Wissahickon, beginning as a small stream fed by underground springs in central Montgomery County, winds its way down into a breathtaking valley in Philadelphia's Fairmount Park before entering the Schuylkill River. Rich in history and scenic beauty, the creek has played a major part in the development of the area. Early mills were established along its banks, and during the American Revolution, Washington's army set up encampments in the creek valley. Since becoming part of Fairmount Park in 1868, the Wissahickon has continued to be the focus of land preservation and is now part of the Wissahickon Green Ribbon Preserve.

Structural Analysis Of The Wissahickon Formation Along The Northern Section Of The Wissahickon Creek Valley, Philadelphia, PA
The structural history of the Wissahickon Formation has been for considerable time questionable and under continuous debate. This current investigation involving the mesoscopic analysis of pelitic schists and psammitic gneisses supported by microscopic study of rock fabrics and thin section analysis discloses a complex structural history consisting of 3 episodes of fold generation. The Primary Structures consist of F1 isoclinal similar folds, L1 lineations (mineral alignments) and S1 axial plane schistosity seen predominantly near the Rosemont Fault Zone. The Second Structures and most predominant are characterized by subisoclinal F2 folds predominantly Class 1C in type, L2 lineations (miner...
