Although the details of the backstory vary from park to park, all follow the same general story arc. Some time in the late 1800s, gold was discovered on Big Thunder Mountain in the American Southwest. Overnight, a small mining town became a thriving one (Rainbow Ridge in Disneyland; Tumbleweed in Florida; Thunder Mesa in Disneyland Paris). Mining was prosperous, and an extensive line of mine trains was set up to transport the ore. Unknown to the settlers, the mountain was a sacred spot to local Native Americans and was cursed.
