Desert Gulch

Desert Gulch serves as one of the major locations in Season 15, and is where the Blues and Reds were originally stationed to while under Project Freelancer. According to Doc, it serves as a prototype to Blood Gulch.

Overview
It is visually similar, if not identical, to it's successor, being primarily filled with dirt, grass, and mountain plains. It is where the Reds and Blues first encounter the Blues and Reds, who reveal that it was their original base. When Tucker finds Doc in their rankings, he reveals that Blues and Reds (and Desert Gulch by association) were the originals while the Reds and Blues were the "crappy copies."

Trivia

 * Because of it's similarity to Blood Gulch, Caboose was able to recognize various areas as if they were in the same location.
