Christiano De Azevedo

Description

The Three Sisters is a worldwide famous landform that is made out of sandstone it consists of three large pillars representing The Three Sisters. It is a landmark of the Blue Mountains. It is an unusual, breathtakingly beautiful rock formation caused by erosion and weathering and this had made it look like three sisters. The height of The Three Sisters is 922m, 918m and 906m. Today it is still getting affected by weathering and erosion. It is very significant to the aboriginals and they have plenty of stories to tell.

The Three Sisters

Human Effect

Activities such as rock climbing, mountain bike riding, horse riding and abseiling caused severe deterioration to the rock face of The Three Sisters. These activities cause erosion by destroying the vegetation that held the thin soil together.

There once was seven rocks but now there are only three.

Aboriginal Dream time Legend

The three magnificent rocks are named Meehni, Wimlah, and Gunneddoo. Their father, a witch doctor named Tyawan. They were from the Katoomba tribe.

The three sisters fell in love with three brothers from the Nepean tribe. Since the tribal law forbids marriage, the brothers wanted to abduct the sisters. An elder from the Katoomba tribe turned the sisters to stone to protect them. There was conflict between the tribes and the elder was killed. As a result, the sisters could not be turned back and today remain as stone.

Aboriginal Dream time story

Geomorphic process 1

Erosion and Weathering

Geomorphic Process

Scientific explanation: Erosion and weathering is the reason why the rock formation is so unique and different. Over time the sun, wind, and rain slowly eroded away at the sandstone which was relatively flat. Wind and rain rubbed against the rock, creating valleys and crevasses. The heat, rain and wind caused the rock to wear away and The Three Sisters was created. Heat, air and water changed the rock shape and erosion is still happening today. In the future, The Three sisters will look very different.

Tectonic plates

Geomorphic process .2

The Three Sisters has a history of uplifts, igneous activity, erosion, sediments deposited and metamorphic changes.

The rocks under the Blue Mountains are about 470 million years old. The Blue Mountains were formed by the pushing and lifting of the tectonic plates. Movement of the earth means the landscape was flooded by the sea which deposited sediment.

About 170 million years ago tectonic activity caused the region to uplift creating a plateau and ending the sand deposition.

The rock arced and flexed under the upward forces. The sandstone broke into vertical cracks. The uplift also caused serious volcanic activity which carried on until about 17 million years ago. Lave spread over the landscape.
