Quarries in Springfield Township included a stone quarry with iron ore deposits at the northwest corner of Walnut Ave. and Oreland Mill Road in Oreland, where Sandy Run Park is now located. In the 1950s, crushed limestone, riprap, road material and railroad ballast were produced by the quarry. It flooded during a spring snow storm that knocked out power, shut down pumps and submerged the quarry. It was purchased by the U.S. Navy in the early 1960s for underwater sonar testing and the site was known as the U.S. Navy Deep Water Facility. Springfield Township accepted ownership of the site from the United States Department of the Interior in 1999 and opened the 14 acre Sandy Run Park. 

Join us, as guest speaker Ronald A. Sloto, research professor of earth and space sciences, West Chester University and author of several books, shares the area’s vast mining history, including information from his 2019 self-published book, The Mines and Minerals of Montgomery County, Pennsylvania.

According to Sloto, the quarries are being filled in and built on. Corson’s Quarry in Plymouth Meeting still operates one while another has been built on and another is being filled in to be built on. Much of Montgomery County was once covered in sand stone, crushed stone, marble and iron.

In his books, which also include The Mines and Minerals of Berks County and The Mines and Minerals of Chester County, Sloto put together his interest in mineralogy, history and geology in one place. While working on the books, he was able to explore some, while others are gone. Sloto worked for 41 years for the U.S. Geological Survey before he began teaching at West Chester University.
