Springfield Township accepted ownership of Sandy Run Park in May 1999 from the United States Department of the Interior. Formerly known as the Cascetti Quarry, mining operations ceased in 1958 after a snowstorm knocked power from the region and the quarry hole filled with water. The United States Navy most recently used the 14 - acre facility for underwater sonar testing. Before opening the facility to the public, the Township plans to hire a consulting firm to develop a Comprehensive Park Master Plan to ensure safe access and use of the park.
