The Flat Top of Mt Kau Kau and Nearby Hills.
In this report I will be highlighting what gave rise to my surface feature, Mt Kau Kau, and explaining the key internal and external geological processes in detail whilst elaborating on the underlying science ideas behind them.
Surface Feature: Mt Kau Kau
Mt Kau Kau is one of the many mountains/hills in the Wellington region and is located on the western side of the Wellington Harbour near Khandallah, Broadmeadows and Johnsonville. Mt Kau Kau is also known as Tarikaka. (See Map #1)
Mt Kau Kau’s summit is 445 meters above sea level and has the Kordia TV transmitter mast on top which is almost 100 meters tall making it very noticeable around Wellington. There is also a Trig station which marks the highest point of Kau Kau.
At the summit of Kau Kau the ground around the lookout and transmitter is relatively flat and in some cases rounded. There is a large stretch of flat land which is about 80 meters long between the Lookout and the Trig Station, on which the transmitter sits on. Also surrounding the Mountain there are multiple gullies where weaker rock and dirt have been weathered and eroded away and in some cases these processes have left chunks of rock revealed. (See Sketch #1)
This flat expanse of land at the top is a remnant of a Peneplain which is also known as a K-Surface that originated in the formation of New Zealand. There are more remaining fragments of the Peneplain scattered around the Wellington region. The Belmont Hills and Quartz Hill are examples of Peneplain remnants which both have reasonably flat surfaces at their summits. (See Picture #1 & #2)
Internal processes which have been involved in the formation of Mt Kau Kau.
The most significant internal processes which have formed Mt Kau Kau have been:
◦Movement along fault lines, such as folding, faulting and uplift.
◦ Plate Tectonics
