Composed of concrete stands overlooking a dirt area where performances were held, now uneven and infested with ants around several anthills. Opposite the stands are several Wild West-themed buildings, the biggest of which is an employee area with lockers, a terminal, and a safe containing the key to Mad Mulligan's Minecart Coaster.
Adjacent to the stands there is a small maintenance building with cabinets and park props inside, while going up the stands provides access to the rooftop of the maintenance building, where the Nuka-Xtreme recipe is located on a table, and the Dry Rock Gulch park flagpole can be accessed.
