Known by a variety of names over its 101-year existence, Rocky Glen Park was a park near Moosic, Pennsylvania. Founded by Arthur Frothingham in 1886 as a picnic park, it was transformed into an amusement park by engineer and entrepreneur Frederick Ingersoll in 1904. 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.
