Mount Melbourne is a 2,733-metre-high (8,967 ft) ice-covered stratovolcano in Victoria Land, Antarctica. It is an elongated mountain with a snow-filled summit caldera and numerous parasitic vents; a volcanic field surrounds the edifice. Mount Melbourne has a volume of about 180 cubic kilometres (43 cu mi) and last erupted between 1862 and 1922. Its volcanism is related both to the West Antarctic Rift and to local tectonic structures such as faults and grabens. Mount Melbourne has mainly erupted trachyandesite and trachyte, which formed within a magma chamber; basaltic rocks are less common. Geothermal heat flow on Mount Melbourne has created an unusual ecosystem formed by mosses and liverworts that grow between fumaroles, ice towers, and ice hummocks. This type of vegetation is found at other volcanoes of Antarctica and develops when volcanic heat generates meltwater from snow and ice, thus allowing plants to grow in the cold Antarctic environment.

Each one claims that their system is the best one for coping with inadequacy. We have to make them all obsolete. We need to find within technology that there is something we can do which is capable of taking care of everybody, and to demonstrate that this is so. That’s what geodesic domes are about and that’s what my whole life has been about. --Buckminster Fuller <https://en.wikiquote.org/wiki/Buckminster_Fuller> _______________________________________________ Wikipedia Daily Article mailing list.
