Course

Mill Creek begins with the confluence of Watson Creek and Lahaska Creek in the central portion of Buckingham Township a short distance south-southeast of the village of Buckingham, flows generally southeast for almost 2.5 miles (4.0 km) to the southwest of Buckingham Mountain where it turns to the east. At the confluence with an unnamed tributary from the left, Mill Creek turns southward for a little more than 0.5 miles (0.80 km). Meeting with another unnamed tributary from the left, it now flows southwestward about another 0.5 miles (0.80 km) until Robin Run joins at Mill Creek's 4.39 river mile from the right where it runs south-southwest for 1.33 miles (2.14 km) to its confluence at Neshaminy Creek's 23.65 river mile just south of Rushland.[4]

Geology

At Mill Creek's headwaters, at the confluence of Lahaska Creek and Watson Creek, is the Allentown Formation, a sedimentary layer of rock deposited during the Cambrian. Mineralogy includes dolomite, limestone, chert, siltstone, oolite, stromatolites, and sharpstone conglomerate.

After a very short distance, it flows into the Leithsville Formation, a sedimentary layer also deposited during the Cambrian. Mineralogy includes dolomite, some containing sand or shale, calcareous shale, and chert.

It then flows into the Brunswick Formation, a sedimentary layer laid down during the Jurassic and Triassic. Mineralogy includes shale, mudstone, siltstone, green and brown shale.

Shortly before it reaches the Neshaminy, it flows into the Lockatong Formation, another formation of sedimentary rock. Mineralogy includes a dark-gray to black argillite, some zones of black shale, and some limestone and calcareous shale.
