 In 1904, Frederick Ingersoll added amusement park rides and concessions, and the newly rechristened Rocky Glen Park, named after the newly-formed Rocky Glen Water Company, became a local sensation.The following year saw the debut of Ingersoll's signature figure eight roller coaster as the Pittsburgh engineer started diverting his energies to his soon-to-open Luna Parks in Pittsburgh and Cleveland (his Luna Park in nearby Scranton was to open the following year).A rift between park owner Frothingham and park manager Ingersoll led to the parting of their ways in 1906.
