Known by a variety of names over its 101-year existence, Rocky Glen Park was a park near Moosic, Pennsylvania, USA. Founded by Arthur Frothingham in 1886 as a picnic park, it was transformed into an amusement park by engineer and entrepreneur Frederick Ingersoll in 1905. The trolley park was a popular Pennsylvania attraction that featured rides, arcades, and restaurants - even as a "wild west" theme park in the 1970s - until its closure in 1987.
