Big Thunder Mountain Railroad is a mine train roller coaster located at Disneyland. Big Thunder Mountain Railroad is also the name of the fictional rail line the roller coaster depicts. While the design of the Walt Disney World version of this roller coaster was done first, Disneyland's version was the first one to open. The track layout was mirrored, placing the attraction to the right of Rivers of America, if viewed from the central hub. In Walt Disney World, the attraction is located to the left of Rivers of America. To better fit with the adjacent Fantasyland areas of the theme park, the original Walt Disney World design had to be replaced with something more appropriate for Disneyland. The Florida, Tokyo and Paris versions of the ride use sharp-edged mountains and the vibrant colors of Monument Valley, Arizona, while Disneyland's version was developed with more rounded features and muted colors resembling the Bryce Canyon hoodoos in Utah.
