If you were a lumberjack in America in the late 1800s, a "log ride" wasn't something you'd line up to do. Log flumes were handmade channels created by loggers to transport felled trees to the sawmill. Stories of lumberjacks riding logs down the flume inspired the many versions of the log rides we know today. The first one, called El Aserradero ("the sawmill" in Spanish), was located at Six Flags Over Texas back in 1963. Passengers boarded a hollowed out "log" and rushed down the flume, getting soaked in the process. The ride was so popular that the park added another log ride a few years later. Famous log rides include Disney's Splash Mountain and Perilous Plunge at Knott's Berry Farm in California, the tallest and steepest log ride with a 115-foot drop.
