Cedar Point posted a recent, high-quality photo of the Leap Frog Scenic Railway to their Facebook page:
This roller coaster has always fascinated me, as the structure spanned a 32 year lifespan across three various roller coaster iterations.
Dip the Dips Scenic Railway originally opened in 1908, with a modest length of 4,200 ft. and tallest drop of 33 ft. It was a part of George A Boeckling's grander plan for transforming Cedar Point from a picnic grove to a nationally-known amusement park and resort area.
The roller coaster operated for ten years, until it was closed and rebuilt as the Leap Frog Railway. The new scenic railway was designed by Andy Vettel (designer of Thunderbolt at Kennywood), and featured a new height of 75 ft. Vettel also designed the Leap the Dips Scenic Railway at Cedar Point, which opened in 1912 and closed in 1934 due to the Great Depression. Leap Frog operated from 1918 to 1933 (pictured above and below):

As the country was pulling out of the Great Depression, the Leap Frog Scenic Railway was revamped in 1933 and reopened as High Frolics. Not much is known on what was changed for High Frolics. At this point however, Cedar Point was in a difficult financial state following the Great Depression (the park was almost sold to the State of Ohio in 1938), and was not able to properly keep their large, wooden coasters in good maintenance. As a result, High Frolics only operated for seven seasons, and was demolished in 1940. Boeckling had also passed away by this point, with new management wanting to focus on renovations to the Coliseum dance floor to draw new crowds for big band performances (additional hotels and restaurants had also been added by this point). After High Frolics' closure, the Cyclone was the only remaining roller coaster at the park, which operated until 1951. While the park added some smaller attractions (and a few wild mouse coasters) along the way, there was a definitive shift away from large roller coaster attractions until later in the 1960s.
