At this time, the continent was covered in a shallow sea. Uluru began its formation underwater until these fans collapsed under the pressure of the water above them. The collapse, and pressure from the sea above fused the plates together. Thus, Uluru was formed. Uluru features a series of steep valleys with large potholes and gaps. These gaps on Uluru have developed due to erosion and will continue to grow over time.
Rainfall slowly flowing down the rockface, and pooling in deeper crevices, will continue to cut away at the rock. The North-West Side The other side of Uluru has seen a different form of Erosion, with large parallel ridges cutting away along the rock.
With rainfall trickling down the same spot of the rock until a long straight gap emerged. Climbing Uluru was once a common practice for tourists, with millions of feet travelling up and down the massive rock every year. The constant travelling along the rockface slowly wore it down, leaving a devastating path. Today it is illegal to climb Uluru, however the damage has already been done. Though this erosion cannot be undone, human feet will no longer make it worse.
As though the rock has been sunburnt and is peeling its top layer. This unique flaking exterior is not due to the sun however by the chemical makeup of the rock. Iron in the rock has slowly rusted over the years, it is this oxidisation that causes a flaky residue. Its Famously Bright Colour If you hear someone talking about Uluru, they are more than likely going to speak about its bright colour.
The reason for its striking colour is due to the iron minerals found within the rock. The iron has slowly rusted over the years rock a bright red colour.
Though hundreds of people head to Uluru every dau, it is the sunset and sunrise that really takes their breath away.
In the mornings, as the warm Australian sun begins to rise, the monolith turns from a milky grey colour to faded purple. As the sun reaches higher the rock glows red, then to a beautiful golden colour, which it remains for the rest of the day. When darkness begins to fall, it goes through another mesmerizing colour shift. Fading from bright red and gold, it becomes a beautiful dusky pink and purple as the sun dips behind the horizon. The colours seem surreal against the wild, sparse landscape.
The clear view of the stars only serves to emphasise the monoliths beauty. For many, it is the promise of a multi-coloured sunset that draws them to Uluru.
The flakes are bits of rock left after water and oxygen have decayed minerals in the rock. Kata Tju t a is made from a conglomerate of pebbles and boulders cemented by sand and mud. Most of the pieces are granite and basalt, which give the conglomerate a plum-pudding effect.
These magnificent rock formations are actually a lot bigger than they appear — like icebergs, most of their mass is below the surface. Ulu r u and Kata Tju t a are only the tips of huge rock slabs that continue underground for up to 6 km! We acknowledge the Traditional Owners of country throughout Australia and recognise their continuing connection to land, waters and culture. We pay our respects to their Elders past, present and emerging.
