Tectonic Planks

The Tectonic Planks is an obstacle, used as the fourth and final obstacle in the Summer Wipeout Zone of Season 5, replacing Iced Over from the Winter Wipeout Zone of the same season. It was interchanged with the 3 C’s of Wipeout as the fourth obstacle throughout the rest of the season.

It consists of two gyrating planks placed beneath four stationary pegs, two above each plank. Contestants must cross and go over at least one peg on each plank to reach the finish platform.

The only contestant who crossed it on their first attempt is Whitney Cordray from episode 9.

In Season 6, it was replaced by both the Bounder Pounder and Twisted Falls.
