Welcome To Mt Wellington
First up please note you have to send me your answers before you log.. Any logs that have not got permission will be deleted straight away.
I hope you are rugged up it sure can be cold up here.....Take extreme care driving and walking around the site, as it can be very slippery on the ice and snow. Please turn on your lights when driving up the mountain.
Firstly do not be mistaken by the idea that Mount Wellington is a dormant volcano, This is incorrect, its not a volcano at all. But A small volcanic vent was active about 300m south of the Pinnacle during Tertiary times, between 50 and 10 million years ago.
The low-lying areas and foothills of Mount Wellington were formed by slow geological upsurge when the whole Hobart area was a low-lying cold shallow seabed. The upper reaches of the mountain were formed more violently, as a Sill with a tabular mass of igneous rock that has been intruded laterally between layers of older rock pushing upwards by upsurges of molten rock as the Australian continental shelf tore away from Antarctica, and separated from Gondwana over 40 million years ago.
The two types of rock mentioned above,
Igneous rock is formed through the cooling and solidification of magma or lava, Dolerite is a sub volcanic rock.
The foothills feature sedimentary sandstones and mudstones laid down during the Permian Period (230-280 million years ago). These are now visible in the foothills of the Mountain around Fern
Tree, South Hobart and Lenah Valley.
Sandstones rich in quartz formed during the Triassic (180-230 million years ago) and covered the
mudstones.
Today these can be seen above approximately 600m in the cliffs and promontories
around the Springs (including Rocky Whelans Cave), Sphinx Rock, Crocodile Rock and Snake Plains.
On the western slopes of the Glen Dhu Rivulet valley the Yellow Cliffs are 50m high and extend for
1km, making it the highest and longest sandstone cliffs in the State.
