After encountering their prey in Steampunk Falls Metal Sonic, E-10000G and Fang split up. Metal Sonic pursues Sonic, Tails and Knuckles into a canyon where he attacks them along with an army of Eggman's robots.
The stage is much like its counterpart Arid Gorge. It has several loops and shortcuts for speed and fly-type
characters. The roads are rather wide and there is sunset. The race begins on an arid surface. The player makes a jump and enters a canyon filed with rocks and deep cracks. The road leads into one of those large cracks. Finally the player enters an underground pump generator which blasts him up on the surface. Near the end of the course there is a long wide road filled with loops and curves. There are thunderbirds flying in the sky.
There are a total of 12 racers in the race: Metal Sonic, Sonic, Tails, Knuckles, SR-4X, SR-4X, SR-4X, SR-4X, SR-4X, SR-4X, SR-4X and SR-4X. The mission of the player is to hit Sonic 5 or more times and finish in 1st or second place.
|Mission||Hit Sonic 5 or more times and finish first or second.|
- The stage is called Thunder Ravine because of the giant thunderbirds that are flying in the sky not because of thunders.
- This stage features the longest rail.
