Yellow Breeches Creek, also known as Callapatscink Creek, Callapatschink Creek (Lenape for "where it returns") or Shawnee Creek is a tributary of the Susquehanna River in central Pennsylvania, USA. There is no agreed upon explanation for the name Yellow Breeches Creek, which is found in land warrants as early as 1736. Description In 1718 Peter Chartier and his father Martin established a trading post about a mile north of the Yellow Breeches along the Susquehanna River. Chartiers Landing was located just off the river between what are now 15th and 16th Streets in New Cumberland, Pennsylvania. Yellow Breeches Creek rises on the northwestern side of South Mountain, in the Michaux State Forest, and collects the drainage of several hollows along the mountainside. It flows north through Walnut Bottom and turns east to run down the Cumberland Valley, paralleled by an ex-Reading Railroad line. It passes through Huntsdale, site of the Huntsdale State Fish Hatchery. The creek begins to meander, and swings around the north side of Mount Holly Springs. Just below the town, it is joined by Mountain Creek. Old Town Run enters just before the creek passes along the south side of Boiling Springs and the spring-fed lake that gives the town its name. The Boiling Springs Lake tributary (photo) enters Yellow Breeches Creek east of the town. The tributary's crystal clear water is a popular trout fishing spot. The creek passes through Williams Grove and meets Dogwood Run just downstream. Below Williams Grove, it forms the boundary between Cumberland and York counties. It flows through the campus of Messiah College, then is joined by Stony Run and enters a series of sharp meanders as the railroad line swings away to the north. Pippins Run joins it, and it flows east to Lisburn, where it makes a sharp turn to flow northwest. It turns north, and then makes a number of meanders to turn east, cutting through the suburbs of New Cumberland. Cedar Run enters near the top of the northernmost meander. It cuts east, then north again, emptying into the Susquehanna. Known for its great fishing, the Yellow Breeches is a popular spot for fly fishers who flock to the mile-long catch and release section near Boiling Springs. Outfitters including Precision Fly & Tackle in Mount Holly Springs offer equipment and advice. The Yellow Breeches is stocked by the Pennsylvania Fish and Boat Commission as well as the
