Echidna Chasm - a very narrow, enchanting slot canyon which is partly only one metre wide. When the sun is high, it reflects on the walls and creates varying colour hues from nearly white to yellow to dark red. (Livistonia ssp.). Bungle Bungle National Park, Purnululu National Park, Western Australia, Australia . At the entrance, the gorge is quite wide and livistonia palms grow on the floor. The high red canyon walls contrast nicely with the green of the plants.
