Magic Kingdom was preparing for its largest expansion. Disney revealed details of Piston Peak National Park, a new area planned for Frontierland.
Inspired by national parks in the Rocky Mountains, the new space promised an immersive, adventurous setting for guests.

Frontierland History and the Arrival of Piston Peak
Since opening, Frontierland has served as a portal to American Old West adventures. With iconic attractions such as Big Thunder Mountain Railroad and, later, Tiana’s Bayou Adventure, the land has taken guests through different historical settings.
Piston Peak was designed to extend that journey with imposing mountains, waterfalls and scenic trails.
What Would Piston Peak National Park Be Like?
Guests were expected to explore a visitor lodge, ranger headquarters and several trails, all within the world of Cars. To help the architecture blend into the landscape, Imagineers worked with the National Park Service (NPS), the U.S. government agency that manages national parks.
Together, they developed the concept of parkitecture, an architectural style created to harmonize construction with the natural environment.
Trees and mountains were also intended to create a visual transition between the former Frontierland and Liberty Square, helping the new area fit organically into the park.
When Did This Magic Kingdom Expansion Begin?
Disney announced permanent closures in the park to build Piston Peak. Beginning July 7, Rivers of America, Tom Sawyer Island and Liberty Square Riverboat were scheduled to close for the project.
The change marked the closure of two original attractions: Rivers of America, which opened in 1971, and Tom Sawyer Island, which opened in 1973.
