How old is Mount Kosciuszko?

Answer 1

Mount Kosciuszko has it origins many millions of years ago when the continents of earth were fused together as the Gondwana land mass. A huge uplift in the earth's crust occurred over millions of years, during the Pliocene and the Pleistocene Epochs (between 5.4 million to 10,000 years ago). This was just after the extinction of the dinosaurs and during the time that modern humans first appeared. This uplift created a super long mountain range. The mountains of the Great Dividing range might have even been hundreds of meters higher, but during the time of the first ice age, hundreds of glaciers replaced the calm streams that run down the mountains, these glaciers carved out all the ridges and rocky walls that we see today, Kosciuszko its a very flat area, scared with glacial lakes, these lakes are all that are left of the glaciers that carved the land.

So to answer your question, Kosciuszko is about 6 million years old, however, this is from when it started forming, which would have taken many many years.
