Ringing Rocks County Park
Ringing Rocks County Park is a Bucks County park in Upper Black Eddy, Pennsylvania at 40°33′47″N 75°07′37″W / 40.56316°N 75.12689°W. Originally, the land was acquired by the Penn family from the Lenape (Delaware Nation) through the infamous 1737 Walking Purchase. It is not clear who made the original land warrant for the area now covered by the Ringing Rocks County Park. On the 1850 property map of Bucks County, the owner appears to be Tunis Lippincott; however, there is no warrantee listing under that name. The earliest published description of the Bridgeton boulder field is found in Davis 1876. The seven-acre boulder field was purchased in 1895 by Abel B. Haring, president of the Union National Bank in Frenchtown, NJ. Apparently Haring wished to protect the ringing rocks from development, and even refused an offer from a manufacturer of Belgian blocks for the right to quarry the stones. (Humphreys 1905, Sigafoos 1935). On August 22, 1918, the land which contains the Bridgeton boulder field was donated by Haring to the Bucks County Historical Society. The grant included 7 acres 8.08 perches of land. A right-of-way was granted by John O. McEntee for access to the park (Fackenthal 1919). Later the land was transferred to Bucks County and operated as a county park. Additional land acquisitions have increased the size of the park to 128 acres.
