Just a short walk from the Organ Pipes is a small inselberg named the Burnt Mountain, proclaimed a national monument on 15 September 1956. The reason for its name is best evident in the early mornings and late evenings when the rays of the sun seem to set the mountain ablaze. Rich red colours mixed with shades of black and purple are quite strikingly caused by Manganese coated clay molecules. During the day, however, the inselberg is just a normal black colour as if the morning fire has burnt it to ashes.
