In 1941–42 J. Frank Sterling, Paul Delgrego, and W. W. Yenney, amateurs who had become interested in collecting local Indian artifacts, excavated a rock .shelter on a stream flowing into Langford Run, near the town of Broomall in Delaware County, Pennsylvania. Langford Run is a tributary of Darby Creek, which in turn flows into the Delaware River from the west at Eddystone, about ten miles southwest of Philadelphia. Further excavation, in a second shelter about 100 yards away from the first, on Langford Run proper, soon uncovered a burial, and contact was established with the University Museum in the fall of 1943 through the good offices of Dr. and Mrs. H. O. Albrecht, members of the Society for American Archaeology.
