The waterfall derives its name from a Thlen or a snake of gigantic size which dwelt in a cave. According to legend the people destroyed the snake in order to rid themselves of its reign of terror. Adjacent to the very spot where the Thlen was slaughtered lies the Dain-thlen Waterfalls. Natural rock carvings of the episode draw visitors to see the image of the Thlen, the symbol of greed, corruption and evil.
