Six Flags Theme Parks originated in 1957 with the creation of The Great Southwest Corporation by Angus G. Wynne and other investors. Construction of Six Flags Over Texas started in 1960 and the park opened the next year for a short (45-day) season. The park initially featured a Native American village, a gondola ride, a railroad, some Wild West shows, a stagecoach ride and “Skull Island”, a pirate-themed adventure attraction. There was also an excursion, inspired by the historical La Salle Expeditions in the late 1600s, called “LaSalle’s River Adventure”, aboard French riverboats through a wilderness full of animated puppets. Over the years, all of those attractions, except the railroad, were replaced by others, such as roller coasters, swing rides, log flumes and shoot-the-chute rides, as well as an observation tower.
