Mill Creek is a small river, also called a "tributary," located in Pennsylvania. It flows into the Neshaminy Creek. Did you know there are many creeks named Mill Creek? This one is special because it's one of three creeks with the same name that flow into the Neshaminy. It's also one of six Mill Creeks found in Bucks County.

Where Mill Creek Flows

Mill Creek starts when two other creeks, Watson Creek and Lahaska Creek, join together. This happens in the middle of Buckingham Township.

From its start, Mill Creek flows mostly southeast for about 2.5 miles (4 kilometers). It then turns east. After a while, it turns south for about half a mile (0.8 kilometers). Then, it flows southwest for another half mile.

Finally, a creek called Robin Run joins Mill Creek. From there, Mill Creek flows south-southwest for about 1.33 miles (2.14 kilometers). It then meets the Neshaminy Creek near a place called Rushland.

Rocks and Geology of the Area

The land around Mill Creek is part of a larger area called the Appalachian Highlands. Specifically, it's in the Piedmont Province. The rocks here tell a long story about Earth's past!

• Allentown Formation: Where Mill Creek begins, the rocks are from the Allentown Formation. These are sedimentary rocks that formed a very long time ago during the Cambrian period. They are made of things like dolomite, limestone, and chert.
• Leithsville Formation: After a short distance, Mill Creek flows over rocks from the Leithsville Formation. These are also sedimentary rocks from the Cambrian period. They contain dolomite and some shale.
• Brunswick Formation: Next, the creek flows over the Brunswick Formation. These sedimentary rocks were laid down during the Jurassic and Triassic periods. They are mostly shale, mudstone, and siltstone.
• Lockatong Formation: Just before Mill Creek reaches the Neshaminy Creek, it flows over the Lockatong Formation. These sedimentary rocks are dark gray to black and include shale and some limestone.
