The Three Sister Formation is 30 km west of Springwood and is the most visited tourist destination in the Blue Mountains.The Blue Mountains were eroded by rivers, ice, and rain from massive slab of sandstone that was up lifted a million years ago. On the left of the first sister you can see a little bridge that leads to the "Giantis Stairway" which descends 300 m via 861 stepsto a walking track at the base of the escorpment.
The Blue haze that gives the Blue Mountains their colour and their name result from the scattering of the sun's rays by tiny droplets of oil that evaporates from the leaves of the eucalypt forest. This eucalyptus oil forms a fine mist above the canopy of the forest and ignites in a bush fire, spreading the fire ahead of the trees and undergrowth burning below the forest canopy. Most native Australian trees have evolved to regenerate after the bush fire has passed. Many have seed pods that do not xxxx --missing word, unless they have been in a fire. The ash from the fire fertilizes the new plants.
