Oil Derrick, Observation tower at Six Flags Over Texas, United States

The Oil Derrick is an observation tower at Six Flags Over Texas that rises approximately 300 feet (91 meters) above the ground. Two elevators transport visitors to viewing platforms where they can see across the surrounding landscape.

The tower was built in 1969 as a replacement for the earlier Sky Hook attraction during the park's expansion phase. This change marked a modernization of the park's offerings in the late 1960s.

The structure reflects Texas industrial heritage through its design, representing the state's historical connection to oil extraction and economic growth. It serves as a visual reminder of the industries that shaped the region's development.

The tower is easy to spot from ground level and locate within the amusement park. The ride up with modern elevators is quick, though wait times can build during busy periods.

The tower's twelve-lane slide was attached at the first balcony level, 50 feet (15 m) up, and riders descended on burlap bags. The source does not record when or whether the slide was removed. The tower replaced the park's earlier Sky Hook attraction.
