Course
Rising from an unnamed pond near Landisville in Plumstead Township at an elevation of 340 feet (100 m), it flows to the southwest through Buckingham Township where it meets the Pine Run Dam and lake, then through New Britain Township, then finally into the Borough of Chalfont where it meets with the North Branch of the Neshaminy at an elevation of 249 feet (76 m). Pine Run has a total length of 7.84 miles (12.62 km) resulting in an average slope of 11.61 feet per mile (2.199 m/km).[4]
Pine Run flows within the Stockton Formation, bedrock laid down during the Triassic, consisting of arkosicsandstone, sandstone, shale, siltstone, and mudstone. Then as it enters Chalfont, it enters the Lockatong Formation, also from the Triassic, consisting of argillite, black shale, limestone, and shale.[5]
