The river passes under a stone arch at the very top of the falls. As the rock is relatively soft, the waterfall has changed over time. Around 1947 the upper half of the waterfall could hardly be seen as the water flowed into a vertical tunnel behind the cliff. It was only visible through three different openings or ‘windows’ one above the other. The water came out through the bottom ‘window’, forming a beautiful arch, except when the water rose in the river, forcing it through all three windows.
